Why Sex Knowledge is of Paramount Importance to Girls and Women—Reasons Why a Misstep in a Girl Has More Serious Consequences than a Misstep in a Boy—The Place Love Occupies in Woman's Life—Woman's Physical Disabilities.
All are agreed—I mean all who are capable of thinking and have given the subject some thought—that for the welfare of the race and for his own physical and mental welfare it is important that the boy be given some sex instruction. All are not agreed as to the character of the instruction, its extent, the age at which it should be begun and as to who the teacher should be—the father, the family physician, the school teacher or a specially prepared book—but as to the necessity of sex knowledge for the boy there is now substantial agreement—among the conservatives as well as among the radicals.
No such agreement exists concerning sexknowledge for the girl. Many still are the men and women—and not among the conservatives only—who are strongly opposed to girls receiving any instruction in sex matters. Some say that such instruction—except a few hygienic rules about menstruation—is unnecessary, because the sex instinct awakens in girls comparatively late, and it is time enough for them to learn about such matters after they are married. Others fear that sex knowledge would destroy the mystery and romance of sex, and would rob our maidens of their greatest charms—modesty and innocence. Still others fear that sex instruction would tend to awaken the sex instinct in our girls prematurely; would direct their thoughts to matters about which they would not think otherwise; and they argue that the warnings about venereal disease, prostitution, etc., which are an integral part of sex instruction, tend to create a cynical, inimical attitude towards the male sex, which may even result in hypochondriac ideas and antagonism to marriage.
I do not deny that there is a grain of truth in all the above objections. Sex instruction does causesomegirls to think of sex matters earlier than they otherwise would, and some girls have been made bitter and hypochondriac, and disgusted with the male sex. But it would not be difficult to demonstratethat it was not sex instructionper sethat was responsible for these deplorable results; it was thewrongkind of instruction that was to blame—it was the wrong emphasis, the lurid exaggerations that caused the mischief, and not the truth. In other words, it is not sex information, it is sex misinformation, that is pernicious. And, of course, to this everybody will agree: rather than false information, better no information at all.
But if the information to be imparted be sane, honest and truthful, without exaggerating the evils and without laying undue emphasis on the dark shadows of our sex life, then the results can be only beneficent. And the task I have put before myself in this book is to give our girls and women sane, square and honest information about their sex organs and sex nature, information absolutely free from luridness, on the one hand, and maudlin sentimentality, on the other. The female sex is in need of such information, much more so than is the male sex. Yes, if boys, as is now universally agreed, are in need of sex instruction, then girls are much more in need of it. Why? For several important reasons.
The first reason why sex instruction is even more important for girls than it is for boys is because a misstep in a girl has much more disastrous consequences than it has in a boy. The disastrousresults of a misstep in a boy are only physical in character; the results of thesamemisstep in a girl may be physical, moral, social and economic. To speak more plainly. If a boy, through ignorance, rashly indulges in illicit sexual relations, the worst consequence to him may be infection with a venereal disease. But he is not considered immoral, he is not despised, he is not ostracized, he does not lose his social standing in the slightest degree, and when he is cured of his venereal disease he has no difficulty in getting married. He does not even have to conceal his past sexual history from his wife. But if a girl makes a misstep the consequences to her are terrible indeed; it may not only cost her her health and social standing, she may have to pay with her very life. She runs the risk of venereal infection the same as the boy does, but in addition she runs the risk of becoming pregnant, which in our present social system is a catastrophe indeed. To save herself from the disgrace of an illegitimate child she may have an abortion produced; the abortion may have no bad results, but it may, if performed bunglingly, leave her an invalid for life, or it may kill her outright. If she is so unfortunate as to be unable to get anybody to produce an abortion, she gives birth to an illegitimate child, which she is forced in most cases to put away in an institution of some sortwhere she hopes and prays it may die soon—and, in general, it does. If it does not die, she has for the rest of her life a Damocles' sword hanging over her head, and she is in constant terror lest her sin be found out. She does not permit herself to look for a mate, but if she does get married, the specter of her antematrimonial experience is constantly before her eyes. After years and years of married life, the husband may divorce her if he finds out that she had "sinned" before she knew him. And unless the husband is a broad-minded man and loves her truly and unless she made a clean breast of everything to him before marriage, her life is continuous torture. But even if the girl escaped pregnancy, the mere finding out that she had an illicit experience deprives her of social standing, or makes her a social outcast and entirely destroys or greatly minimizes her chances of ever marrying and establishing a home of her own. She must remain a lonely wanderer to the end of her days.
The enormous difference in the results of a misstep in a boy and a girl is clearly seen, and for this reason alone, if for no other, sex instruction is of more importance to the girl than it is to the boy.
But there are other important reasons, and one of them is beautifully and truthfully expressed by Byron in his two well-known lines.
Man's love is of man's life a thing apart,[30]'Tis woman's whole existence.
Man's love is of man's life a thing apart,[30]'Tis woman's whole existence.
Yes, love is a woman's whole life.
Some modern women might object to this. They might say that this was true of the woman of the past, who was excluded from all other avenues of human activity. The woman of the present day has other interests besides those of Love. But I claim that this is true of only a small percentage of women; and in even this small minority of women, social, scientific and artistic activities cannot take the place of love; no matter how busy and successful these women may be, they will tell you if you enjoy their confidence that they are unhappy, if their love life is unsatisfactory. Nothing, nothing can fill the void made by the lack of love. The various activities may help to cover up the void, to protect it from strange eyes, they cannot fill it. For essentially woman is made for love. Not exclusively, but essentially, and a woman who has had no love in her life has been a failure. The few exceptions that may be mentioned only emphasize the rule.
But not only psychically is a woman's love and sex life more important than a man's, physically she is also much more cognizant of her sex and much more hampered by the manifestation of her sexnature than man is. To take but one function, menstruation. From the age 13 or 14 to the age of forty-five or fifty it is a monthly reminder to woman that she is a woman, that she is a creature of sex; and, while to many women this periodically recurring function is only a source of some annoyance or discomfort, to a great number it is a cause of pain, headache, suffering, or complete disability. Man has no such phenomenon to annoy him practically his whole life.
But more important are the results of love-union, of sex relations. A man after a sexual relation is just as free as he was before. A woman, if the relation has resulted in a pregnancy, which is generally the case, unless special pains are taken it should not so result, has nine troublesome months before her, months of discomfort if not of actual suffering; she then has an extremely trying and painful ordeal, that of childbirth, and then there is another trying period, the period of lactation or of nursing and of bringing up the baby. The penalty seems almost too great.
And when the woman is on the point of ceasing to menstruate she does not do so smoothly and comfortably. She has to go through a period called the menopause, which may last one or two years and which may bring discomforts and dangers of itsown. Man does not have to go through such a distinct period of demarcation separating his sexual from his non-sexual life. Altogether it cannot be denied that woman is much more a slave of her sex nature than man is of his. Yes, Nature has handicapped woman much more heavily than she has man.
In short, both in view of the fact that sexual ignorance with its possible missteps has much more disastrous consequences for the girl than it has for the boy, and in view of the fact that the sex instinct and its physical and psychic manifestations occupy a much more important part in woman's life than they do in the life of man, we consider the necessity of sex instruction much greater in the case of woman than in the case of man. I do not wish to be misunderstood as underestimating the need of sex instruction for the male—only I consider the need even greater in the case of the female.

The organs which primarily distinguish one sex from the other are the sex organs. It is by the aid of the sex organs that children are begotten and brought into the world, that the race isreproducedand perpetuated. It is for this reason that the sex organs are also called the Reproductive Organs.
The first thing we must do is to become familiar with thestructureandlocationof the sex organs; in other words, we must get a fair idea of theirAnatomy.
The female sex organs, also called the reproductive or generative organs, are divided into internal and external. The internal are the most important and consist of: the ovaries, Fallopian tubes, uterusor womb, and vagina. The external sex organs of the female are: the vulva, hymen, and clitoris. Among the external organs are also generally included the mons Veneris and the breasts or mammary glands.
The Ovaries.The ovaries are the essential organs of reproduction. For it is they that generate the eggs, orova, orovules, which, after becomingfertilizedorfecundatedby the spermatozoa of the male, develop into children. Without the ovaries of the female, the same as without the testicles of the male (to which they correspond), no children could be begotten, and the entire human race would quickly disappear from our planet. The ovaries are two in number; they are embedded in thebroad ligamentswhich support the womb in the pelvis, one on each side of the womb. They are of a grayish or whitish pink color, and are about an inch and a half long, three-quarters of an inch wide, and one-third of an inch thick. They weigh from one-eighth to one-quarter of an ounce. Their surface is either smooth or rough and puckered. Think of a large blanched almond and you will have a pretty fair idea of the size and shape of an ovary.

The Fallopian Tubes.The Fallopian tubes (so called from Fallopius, a great anatomist, who discovered them; also called oviducts: egg conductors, because they conduct the eggs from the ovary into the uterus) are two very thin tubes, extending one from each upper angle of the womb to the ovaries; but at their ovarian end they expand into a fringed and trumpet-shaped extremity. The fringes are referred to asfimbria. They are about five inches long and only about one-sixteenth of an inch in diameter; the function of the tubes is to catch the ova as they burst forth from the ovaries and to convey them to the uterus. Taking into consideration the very narrowlumen, orcaliber, of the Fallopian tubes, it is easy to understand why even a very slight inflammation is apt to clog them up, to seal their mouths or openings, thus rendering the womansterile, or incapable of having children. For, if the Fallopiantubes are "clogged" up, the eggs, or ova, have no way of reaching the uterus.
The Greek name for the Fallopian tube is salpinx (salpinx in Greek means tube). An inflammation of the Fallopian tube is therefore called salpingitis. (A salpingitis has the same effect in causing sterility in the female as has an epididymitis in the male.) Salpingectomy is the cutting away of the whole or of a piece of the Fallopian tube (corresponds to vasectomy in the male).

The Uterus.The uterus or womb is the organ in which the fertilized ovum, or egg, grows and develops into a child. It is a hollow muscular organ, about the size of a pear, with thick walls, capable under the influence of pregnancy of great expansion and growth. The broad part of the pear is called thebodyof the uterus; the lower narrow part is called theneckof the uterus, orcervix. The uterus in the adult girl or woman is about three inches long, two inches broad in its upper part and nearly an inch thick. It weighs from an ounce to an ounce and a half. When the uterus is in a pregnant condition, it increases enormously, both in size and in weight, as we will see in a future chapter. The cavity of the uterus is somewhat triangular in shape; at each upper angle is the small opening communicating with the Fallopian tube; the upper portion ofthe uterus is called the fundus; the external opening of the womb, situated in the center of the cervix, is called the mouth of the womb, or theos, or external os.
The uterus is situated in the center of the pelvis, between the bladder and the rectum. It is supported by certain ligaments, the chief of which are the broad ligaments; but, on account of general weakness, too hard physical labor, or lifting heavy weights, the ligaments may stretch, and the uterus may sink down low in the vagina, and we then have the condition known as prolapse of the womb. Or, the womb may turn forward, when we have a condition ofanteversion. If the womb isbent(orflexed) forward on itself the condition is calledanteflexion. If the womb is turned backwards, the condition is calledretroversion; if it is bent or flexed backward upon itself the condition is calledretroflexion. An extreme degree of anteversion or anteflexion, or retroversion or retroflexion, may interfere with impregnation, as the spermatozoa may find it difficult or impossible to reach the opening of the womb—the external os.
Womb.
The entire cavity of the uterus is lined by a mucous membrane;[1]this mucous membrane is called the endometrium (endo—within; metra—uterus). An inflammation of the endometrium is calledendometritis. It is the endometrium that is principally concerned in menstruation—that is, it is from it that the monthly discharge of blood comes.
The Vagina[vagina in Latin—a sheath]. The vagina is the tube or canal which serves as a passage-way between the uterus and the outside of the body. It extends from the external genitals or vulva to the neck of the womb, embracing the latter for some distance. It is a strong, fibromuscular canal, lined with mucous membrane. It is not smooth inside, but arranged in folds, orrugæ, so that when necessary, as during childbirth, it can stretch enormously and permit the passage of a child's head. The length of the vaginal canal is between three and five inches, but it is in general much more capacious in women that have borne one or more children than in those who have not borne any.
Near the vaginal entrance are situated two small glands; they are about the size of a pea, and secrete mucus. They are called Bartholin's glands; occasionally they become inflamed and give a good deal of trouble.

The Hymen[hymen in Greek—a membrane]. The external opening of the vagina, in virgins, that is, in girls or women who have not had sexual intercourse, is almost entirely closed by a membrane called the hymen. The vulgar name for hymen is "maidenhead." The hymen may be of various shapes, and of different consistency. In some girls it is a very thin membrane, which tears very readily; in others it is quite tough. On the upper margin or in the center of the hymen there is an opening which permits any secretion from the vagina and the blood from the uterus to come through. In rare cases there is no opening in the hymen, that is, the vagina is entirely closed. Such a hymen is calledimperforate(not perforated). When the girl begins to menstruate, the blood cannot come out and it accumulates in the vagina. In such cases the hymen must be opened or slit by a doctor. In some cases the hymen is congenitally absent; that is, the girl is born without any hymen. While the hymen is usually ruptured during the first intercourse, it, in some cases, being elastic and stretchable, persists untorn after sexual intercourse. It will therefore be seen that just as the presence of the hymen is no absolute proof ofvirginity, so is the absence of the hymen no absolute proof that the girl has had sexual relations, She might have been born without any hymen, or it might have been ruptured by vaginal examination, by a vaginal douche, by scratching to relieve itching, or by some accident.
The remains of the hymen after it is ruptured shrink and form little elevations which can be easily felt; they are known as caruncles. [In Latin,carunculæ myrtiformes, which means in English myrtleberry-shaped caruncles; caruncle is a small fleshy elevation; derived fromcaro, which in Latin means flesh.]
The Vulva.The external genitals of the female are called thevulva. The vulva consists of the labia majora (meaning the larger lips), which are on the outside and which in the grown-up girl are covered with hair, and the labia minora (the smaller lips), which are on the inside and which are usually only seen when the labia majora are taken apart.
[Vulva in Latin means folding-door. The ancients Were fond of giving fancy names to things.]
The Mons Veneris.The elevation above the vulva,which during puberty becomes covered with hair, is called by the fanciful name,mons Veneris, or Venus' mountain. It is usually well padded with fatty tissue.
The Clitoris.The clitoris is a small body about an inch in length, situated beneath the mons Veneris and partly or entirely covered by the upper borders of the labia minora.
The Urethra.Between the clitoris above and the opening of the vagina below is situated the opening of theurethra, or the urinary meatus, through which the urine passes. Many women are so ignorant, or, let us say innocent, that they think the urine passes out through the vagina. This is not so. The vagina has nothing to do with the process of urination.
Again enumerating the female sex organs, but in the reverse order, from before backward, or from out inward, we have: The mons Veneris and the labia majora, or the external lips of the vulva; these are the plainly visible parts of the female genital organs. When the labia majora are taken apart we see the labia minora; when the labia majora and minora are taken apart we can see or feel the clitoris and the hymen, or the remains of the hymen. We then have the vagina, a large, stretchable musculo-membranous canal, in the upper portion of which the neck of the womb, or the cervix, can be seen(when a speculum is used), or felt by the finger. Only the cervix, or neck of the womb, can be seen, but the rest of the womb, the broader portion, can be easily felt and examined by one hand in the vagina and the other hand over the abdomen. Continuous with the uterus are the Fallopian tubes, and below the trumpet-shaped ends of the Fallopian tubes are the ovaries, embedded in the broad ligaments, one on each side.
The Breasts.The breasts, also called mammary glands, or mammæ [mamma in Latin, breast], may be considered as accessory organs of reproduction. They are of no importance in the male, in whom they are usually rudimentary, but they are of great importance in the female. They manufacture milk, which is necessary for the proper nutrition of the infant, and they add a great deal to the beauty and attractiveness of the woman. They are thus a help to the woman in getting a mate or a husband. The projecting elevation of the breast, which the child takes in his mouth when nursing, is called the nipple; the darker colored area surrounding the nipple is called the areola.

The Pelvis of the Female.
The internal sex organs are situated in the lower part of the abdominal cavity, the part that is called thepelvis, or pelvic cavity. The meaning of the word pelvis in Latin is basin. The pelvis, also referred to as the pelvic girdle or pelvic arch, forms a bony basin, and is composed of three powerful bones: the sacrum, consisting of five vertebræ fused together and constituting the solid part of the spine, or vertebral column, in the back, and the two hipbones, one on each side. The two hipbones meet in front, forming thepubic arch.
The hipbones are called in Latin the ossa innominata (nameless bones) and each hipbone is composed of three bones: the ilium, the ischium, and the os pubis. The thighs are attached to the hipbones, and to the hipbones are also attached the largeglutealmuscles, which form the buttocks, or the "seat."
The pelvis of the female differs considerably from the pelvis of the male. The female pelvis is shallower and wider, less massive, the margins of the bones are more widely separated, thus giving greater prominence to the hips; the sacrum is shorter and less curved, and the pubic arch is wider and morerounded. All this is necessary in order to permit the child's head to pass through. If the female pelvis were exactly like the male pelvis, a full-term living child could never pass through it. The two illustrations show the differences between the male and female pelvis very clearly.
Note particularly the differences in the pubic arches: in the male pelvis it is really more of an angle than an arch. Also note how much longer and more solid the sacrum (with its attached bone, called the coccyx[2]) is in the male pelvis. The differences in the pelves (the plural of pelvis is pelves) of the male and female become fully marked at puberty, but they are present as early as the fourth month of intra-uterine life.

The importance of an organ depends upon itsfunction, upon what it does, and not so much upon what it is. It is important to know the size, structure and location of an organ, but it is still more important to know its function; in other words, for our purpose it is more important to know thephysiologythan the anatomy of the sex organs.
Like the testicles in man, so the ovaries in woman are the essential sexual organs. They are the fundamental organs, without which the other sexualorgans are useless. Also like the testicles in man, the ovaries have two distinct functions, manufacturing two distinct substances. One function is to manufacture eggs; this, called the oögenetic or egg-producing function, is itsracialfunction; without it the race could not perpetuate itself. But the ovary has also anindividualfunction. Besides the ova, the ovary manufactures what we call aninternalsecretion which is absorbed by the blood, and which is of the greatest importance to the woman herself. While the manufacture of ova begins only at puberty, with menstruation, and closes at the menopause, the manufacture of the internal secretion lasts throughout the woman's entire life. This secretion, which consists of various chemical substances, has a tremendous influence not only on the development of the woman's body, but also on her feelings.
First of all it is necessary for the development of the woman's special characteristics, orsecondary sexual characters. Without that internal secretion of the ovaries, a woman would look more or less like a man; she would not develop her beautiful rounded form, her pretty long hair, her breasts, her broad pelvis, her feminine voice, etc.Second, the secretion is necessary to the proper development of her other sexual organs; if the ovaries are cutout, then the uterus and the vagina and even the vulva shrivel up.Third, it is that internal secretion that excites in woman sexual desire and makes her enjoy relations with the male sex. If the ovaries are cut away, particularly if it is done early in life, the woman has no sexual desire and no enjoyment.Fourth, it contributes to the general health, wellbeing, energy, and mental alertness of the woman.
You see the importance of the internal ovarian secretion, and you will readily understand why, when the ovaries are removed by operation, the woman, particularly if she is young, undergoes such marked changes. It is because we recognize now the great importance of the ovaries that we always, when operating on diseased ovaries leave at least a small piece of ovary, if at all possible.
Number of Ova.When the female infant is born, her ovaries contain as many ova or eggs as they ever will contain. In fact, they contain more than they will at puberty. For it is estimated that at birth each ovary contains about 100,000 ova; the majority of these, however, disappear so that at the age of puberty each ovary contains only about 30,000 ova. As only one ovum ripens each month from the time of puberty to the time of the menopause (i.e., about 300 to 400 ova at the utmost duringa lifetime), and as only a dozen or two ova would be necessary for the propagation of the race, it seems a superabundance of ova, an unnecessary lavishness. But natureislavish where the propagation of the species is concerned. A portion of an ovary or of both ovaries might become diseased, and thousands of ova might become unfit for fertilization; nature therefore puts in an extra reserve supply. We see a still more striking example of this extreme extravagant lavishness in man; only one spermatozoön is necessary to impregnate the ovum, and only one spermatozoön can penetrate the ovum; nevertheless each normal ejaculation of semen contains between a quarter and half a million spermatozoa.
The Graafian Follicles.Each primitive or primordial ovum[3]is imbedded in a little vesicle or follicle, which is generally known asGraafian follicle, and there are as many Graafian follicles as there are ova. (The Graafian follicles were first described about 250 years ago—in 1672—by a Delft physician named De Graaf, hence the name.) Until puberty, that is the commencement of menstruation, the Graafian follicles with the oöcytes or primitiveova are in a more or less dormant condition. But with the onset of puberty there commences a period of intense activity in the ovaries. This period of activity is repeated regularly once a month, and it constitutes the process ofovulationandmenstruation. The two processes are closely though not causally connected. Ovulation consists in the monthly maturation and extrusion of a ripe ovum; menstruation, which will be further discussed in a separate chapter, consists in the monthly discharge of blood, mixed with mucus from the inside lining of the uterus. Every twenty-eight days, from thetime of puberty to the time of the menopause, a Graafian follicle bursts and an ovum is extruded from the ovary. Before the follicle bursts, it swells and enlarges and reaches the surface of the ovary; the whole follicle is congested with blood, but at one point near the surface of the ovary it is pale and thin, and here the rupture takes place.

Corpora Lutea.After the Graafian follicle has burst and the ovum has been pushed out, the cavity that is left does not remain empty and functionless; there is a further process going on there; there is a growth of cells, of a yellowish color, and the follicle becomes filled with a yellowish body, which on account of its color is called thecorpus luteum(plural—corpora lutea; luteum in Latin—yellow, corpus—body). This corpus luteum grows in size until it sometimes occupies as much as one-third of the ovary. But there is considerable difference between the corpora lutea of non-pregnant and pregnant women. Up to the end of about a month the corpora lutea are the same, but after that the corpus luteum of the non-pregnant woman begins to get smaller, to shrink, so that at the end of two or three months it is reduced to a small scar and later cannot be noticed at all. The corpus luteum of the pregnant woman keeps on increasing until the end of the second month, remains about the same sizeuntil the end of the sixth month, and only then begins gradually to diminish. The corpus luteum of the non-pregnant woman, that is, the one following menstruation, is called false corpus luteum; the corpus luteum following pregnancy is called a true corpus luteum. The corpus luteum acts like a gland and elaborates a secretion which has an influence on the circulation in the uterus and on menstruation. It probably possesses other properties, with which we are not yet quite familiar. The corpora lutea of various animals are now prepared in powder or tablet form and used in medicine in the treatment of certain diseases of women.
Function of the Fallopian Tubes.The function of the Fallopian tubes or oviducts as they are sometimes called is to catch the ovum as it bursts through the ovary and to conduct it from the ovary into the uterus. It is while the ovum is in the narrow lumen of the tube that the spermatozoön which has travelled up from the uterus usually finds it, and it is in the tube, near its entrance to the womb, that impregnation usually takes place. After the ovumis impregnated or fecundated, it slowly moves down to the uterus, where it attaches itself and remains and grows for nine months, until it is ready to come out and start an independent life.
The uterus or womb is the house of the embryo almost from the moment of conception to the moment of birth. Within the thick warm sheltered walls of the uterus the child grows, develops, eats and breathes, until all its organs and functions have reached such a stage of perfection that it can live by itself and for itself. And this may be said to be the sole function of the uterus, or at least its sole useful function. For the other function of the uterus, menstruation, cannot be said to be a necessary or a useful function. It is a normal function because it occurs regularly in every healthy woman during her child-bearing period, but not every normal function is a necessary or useful function. Not everything that is is right or useful.
Function of the Vagina.The vagina is the canal in which sexual intercourse takes place. It receives the male organ (penis) during the sexual act, and serves as a temporary repository for the male semen. After the spermatozoa have reached the uterus, the vagina has no further function to perform.
Functions of the Vulva, Clitoris, andMonsVeneris.The vulva and the clitoris have no special functions to perform; but in them, in the clitoris particularly, but also in the labia minora, resides the feeling of voluptuousness, the pleasurable sensation experienced during the sexual act. Another seat of voluptuousness in the woman is located in the cervix of the uterus.
The mons Veneris has no special physiological function to perform, but it as well as the vulva serve as strong points of attraction for the male sex. While the entire female body is attractive to the male, and vice versa, there are certain zones which are especially attractive or exciting. Such zones or areas are callederogenous zones—the word erogenous means love-generating. The vulva and the mons Veneris are the strongest erogenous zones; other erogenous zones are the lips, the breasts, etc.
Function of the Breasts.The function of the breasts is to nurse or suckle the young on the mother's milk until they are able to live on other food. The other name for breasts is mammary gland (in Latin, mamma—breast), and all animals who suckle their young are called mammals or mammalia. Besides its milk secreting function, the breasts constitute a strong erogenous zone; they are a point of strong attraction for the male sex, many men being more attracted by well-developed breasts thanby a pretty face. There is a good biological reason for this. Well developed breasts indicate that the other sexual organs are well developed and that the woman will make a satisfactory wife and satisfactory mother. Considering then the importance of the breasts in attracting a husband and their function in nursing the young, also their erogenous properties, it is perfectly proper to class them among the reproductive organs.
The culmination of the act of sexual intercourse is called the orgasm. It is the moment at which the pleasurable sensation is at its highest point, the body experiences a thrill, there is a spasmodic contraction in the genital organs, and there is a secretion of fluid from the genital glands and mucous membranes. This fluid in women is not a vital fluid like the semen in man; it is merely mucus, and in some women it is very slight in amount or altogether absent. Adult women who live without sexual relations occasionally have sexual or erotic dreams; that is, they dream that they are in the company of men, playing or having relations withthem. Such dreams are usually accompanied by an orgasm or an orgastic feeling, and by a discharge of mucus, the same as in sexual intercourse. Such a discharge of mucus during sleep is called an emission or pollution.
In the male sex pollutions play an important rôle (see the author's "Sex Knowledge for men"), because the semen is a vital fluid, and if it is lost too frequently the system is put under a heavy drain. In boys and men the pollutions or night losses may occur several times a week or even every night, or several times a night. When they occur with such frequency the man may become a wreck. Not so with women. First, pollutions or night dreams in women are much more rare than they are in men; and second, as just mentioned, the fluid secreted by woman during intercourse or during an erotic dream is not of a vital character, as the semen is in man; it is mucus, and the secretion of a mucous fluid, even if somewhat excessive, does not constitute a drain on the system. For this reason women can stand frequently repeated sex relations and emissions or pollutions much better than men can.
