The case I have now to describe is that of a woman whose characteristics during childhood were thoroughly boyish, and who at this time experienced homosexual inclinations; during the period of the puberal development, however, the homosexual tendencies disappeared, never to return.

Case 10.—Mrs. X., twenty-six years of age, happily married for five years past, enjoys excellent health, with the exception of pains during menstruation, has normal intercourse with her husband, experiencing sexual impulse of full intensity, and a normal voluptuous sensation. The family history is healthy on the whole; some of the mother's relatives are described as "nervous"; but in so large a family, otherwise healthy, this is of trifling significance. Most of her blood-relations are, so far as inheritable morbid conditions are concerned, thoroughly healthy. As a girl, X. (whose statements, in so far as I was able to inquire, were in all important respects substantiated by her mother) was at first accustomed to seek the companionship of boys only. She was continually playing with her brothers and their friends, and was always the leader in their wildest games including war-games, and playing at Indians. During childhood she was almost always regarded as "the baby," although she had a sister two years younger than herself, this sister being altogether girlish in her ways. Very seldom did X. play with anyone but the boys; when she did on rare occasions seek other companionship, it was always that of the sister of one of her boy friends. The two girls had obviously great sympathy each for the other, manifested when they were as yet only nine years of age, and increasing as the years went on. The closer her association became with this girl, the more did X. withdraw from the companionship of the boys, to devote herself to her girl friend. The association became more and more intimate; and when they were both thirteen years old their endearments passed from kisses and embraces to manipulation of the genital organs. In these latter, X. always played a passive part, not herself touching her own genital organs nor those of her friend. Occasionally X. would feel drawn towards some other girl, but such errant inclinations never lasted long. At about the time when her fondness for the other girl began, that is to say, during her tenth year, X., who was then accustomed to compassionate herself for not having been born a boy, began to assume a more definitely boyish behaviour. Under the pretence of "dressing up," she used to wear her brother's clothes; occasionally she smoked, although in her home, and in the circle to which her family belonged, smoking was disapproved of even in grown women. At the age of fourteen, X. began to menstruate. The friendship between the two girls continued until the seventeenth year of life. Then X. gradually "came out," her homosexual tendencies disappeared, and at the same time her feminine nature became apparent. The desire to dress up as a man and the desire to smoke passed away, and have never returned, although X. now moves in circles in which many women smoke. And, most important fact of all, the homosexual relations were now completely broken off. The two girls remained on friendly terms; but alike in X. and in her friend the homosexual inclinations disappeared, and the improper sexual practices were entirely discontinued. X. began to flirt, now with one man, now with another, until when nineteen years old she fell in love with her present husband, and married him after a two years' engagement.

This case shows that neither the existence of homosexual inclinations during childhood, nor the simultaneous exhibition of other contrary sexual mental qualities, necessarily foreshadows the development of permanent homosexuality. On the other hand, we must not from the subsequent appearance of heterosexuality draw the conclusion that this was first acquired intra vitam, for it very often happens that congenital heterosexuality first manifests itself during the period of the puberal development. In an analogous case, in which the homosexual and other contrary sexual tendencies and inclinations of childhood have persisted during the adult sexual life, it would be equally erroneous in the absence of further evidence to conclude that the homosexuality was congenital. I recognise the existence of congenital homosexuality, but I consider that the reality of this condition is established by other grounds than those just mentioned. This question has been fully discussed by me elsewhere,[57] and cannot here be further considered.

Many investigators regard homosexuality as an acquired manifestation. In cases in which the existence of homosexuality can be traced back into childhood, they explain this on the ground that at a time when the individual concerned was in a state of sexual excitement, some other person of the same sex must have made a marked impression upon his imagination. In this way, they suggest, is effected an association whose influence endures throughout life. I will here say no more than this, that this association theory does not suffice to account for the facts. The deficiencies of the association theory will to some extent become apparent from the account I am about to give of the other sexual perversions.

For the dispute to what extent sexual perversions are congenital and to what extent they are acquired, prevails not only concerning homosexuality, but also concerning sadism, masochism, sexual fetichism, &c. In the case also of these latter perversions, some maintain that in those instances in which the perversion began in childhood, some early association was the originating cause; whilst others, from the very fact that the perversion appeared very early in life and was apparently primary, infer that it must be of a congenital character. For instance, a man experiences sexual excitement whenever he sees a cook or other woman kill a fowl; and when revived in memory, the corresponding ideas exercise a similar exciting influence. On inquiry, we learn that when he was eight years old he by chance saw a fowl killed, and then immediately felt strong sexual excitement. Similarly, many masochists and sadists assure us that their first experience of their peculiarly tinged sexual excitement occurred during childhood; e.g., in the case of the masochist, when being punished with a whipping, and so on.

Beyond question, the impressions of childhood may result in the formation of enduring associations. From experiences during childhood may originate terrors and feelings of disgust which are never subsequently overcome. A child who for any reason has several times felt a strong loathing towards some particular article of food, will retain throughout life a dislike to this same substance. Felix Platter relates his own experience as follows. When a child, he once saw his sister slicing rings of "boiled gorge" (see note, below.), and sticking these rings on her finger. The sight was so unpleasant to him that he had to go away. The disagreeable memory has been so persistent, that ever since he has been unable to bear the sight, not merely of such "rings of flesh," but rings of gold, silver, or any other material. A child who has once been frightened by a dog, may ever after be terrified of all dogs. An individual may also, by a kind of moral contagion, be affected by the experiences of others. A child who has seen another child frightened by a cat, may for this reason acquire an antipathy to cats lasting for the whole of life. It is upon the undoubted fact of such experiences as these, that those build their case who maintain that sexual perversions originate in chance impressions during childhood or early youth. But weighty reasons can be alleged against any such generalisation.

Note on the expression "Boiled Gorge."—This is a literal translation of the German gesottne Gurgeln, an apparently forgotten article of diet. Finding no account of it in any German dictionary, I applied to Dr. Moll, who writes as follows:—"Gurgel denotes a particular part of the neck, in human beings the front part, comprising the hyoid bone, the larynx and trachea, the pharynx and the upper part of the oesophagus, the thyroid body, and the adjoining muscles. As far as I am aware, this part of the animal body is not now used for food. Presumably it was so used in Felix Platter's time, but I cannot say if the 'rings' of which he speaks were cut from the trachea, the oesophagus, or perhaps the great blood-vessels."—Translator's Note.

To return to the instance of the man who is sexually excited by the sight of fowls being killed, it is true that on superficial consideration the case may appear to support the theory that we have here to do with an acquired perversion. We cannot assume that in this child the complicated image of the killing of a fowl was inborn, and the first inference will therefore be that his perversion is purely an acquired one. But on closer examination we perceive that the matter is less simple than appeared at first sight. First of all we have to inquire why it is that in this particular instance the sight of the killing of a fowl induced such a perversion, when in hundreds of other cases no such result follows the same stimulus. The assumption that in the particular case there chanced to occur sexual excitement simultaneously with the sight of the fowl-killing, is altogether inadequate as an explanation. For, first, this assumption of the simultaneous occurrence of sexual excitement is in most cases a pure supposition, quite unsupported by proof. Secondly, even when the two processes, the sight of the killing, and the sexual excitement, do occur simultaneously, it is still open to question whether the latter may not have been determined by the former; that is to say, it may be that the perverse mode of sexual sensibility previously existed, at least as a predisposition, and that the connexion between the phenomena is the reverse of what is supposed. Thirdly, moreover, the chance view of some occurrence in association with sexual excitement does not suffice to explain the enduring association of sexual excitement with such an occurrence throughout the whole of life. Think of persons who have masturbated during childhood. When they were masturbating, their eyes have rested on various indifferent objects: underlinen, articles of furniture, pictures, books, &c.; but this does not induce the association throughout life of sexual excitement with the sight of any of these articles.

Apart from these considerations, the fact that some external process, such as the killing of a fowl, has important relationships with the content of a subsequent perversion, does not prove that this perversion is an acquired one. We may rather suppose that in the case of one endowed with a congenital predisposition to the excitement of the sexual impulse by the sight of cruelty, the particular cruel act which will prove the determinant in a particular case, must depend upon the chance circumstances of the individual's life. On this view, if, in the case under consideration, the fowl-killing had not happened, at the appropriate time, to awaken the sexual impulse, it must be assumed that some other but similar process would have been competent to effect this. In any case, the association theory alone will not suffice to account for these cases; and the possibility cannot be excluded that in cases of sadism there is a specific abnormal disposition of the sexual impulse, and that the experiences during childhood influence the matter only in so far as they may determine the special manner in which the sadistic tendency will subsequently manifest itself. It is, in fact, very remarkable how often some particular act of cruelty will, in a certain individual, exercise throughout life a sexually exciting influence: in one person the desire to strike may be associated with sexual excitement; in another it may be the desire to stab or to cut; in one individual sexual excitement results from the sight of a fowl being killed; in another, when the victim is a fish, and so on. Although we encounter some in whom the particular cruel act associated with sexual excitement changes many times during life; yet, on the other hand, we find that there are many persons in whom sexual excitement is aroused by some special sadistic practice, and by that alone; and on careful inquiry we ascertain that even in childhood such an act was associated with voluptuous excitement.

I will take this opportunity of explaining very briefly that there is still another possible way of explaining these enduring associations as being based upon impressions received during childhood, without the supposition that these impressions of childhood are the exclusive determinants; this is the assumption that there exists a congenital weakness of the rudiment of the normal sexual impulse, and that it is owing to this primary defect that the paths of nervous conduction involved in the activity of the normal sexual impulse so readily become impassable.
