It is a very remarkable fact that, although for many years past serious attempts have been made to elucidate the psychology of sexual perversions, little or no endeavor has been made to study the development of the normal sexual emotions. Nearly every writer seems either to take for granted that he and his readers are so familiar with all the facts of normal sex psychology that any detailed statement is altogether uncalled for, or else he is content to write a few fragmentary remarks, mostly made up of miscellaneous extracts from anatomical, philosophical, and historical works.

Yet it is as unreasonable to take normal phenomena for granted here as in any other region of science. A knowledge of such phenomena is as necessary here as physiology is to pathology or anatomy to surgery. So far from the facts of normal sex development, sex emotions, and sex needs being uniform and constant, as is assumed by those who consider their discussion unnecessary, the range of variation within fairly normal limits is immense, and it is impossible to meet with two individuals whose records are nearly identical.

There are two fundamental reasons why the endeavor should be made to obtain a broad basis of clear information on the subject. In the first place, the normal phenomena give the key to the abnormal phenomena, and the majority of sexual perversions, including even those that are most repulsive, are but exaggerations of instincts and emotions that are germinal in normal human beings. In the second place, we cannot even know what is normal until we are acquainted with the sexual life of a large number of healthy individuals. And until we know the limits of normal sexuality we are not in position to lay down any reasonable rules of sexual hygiene.

On these grounds I have for some time sought to obtain the sexual histories, and more especially the early histories, of men and women who, on prima facie grounds, may fairly be considered, or are at all events by themselves and others considered, ordinarily healthy and normal.

There are many difficulties about such a task, difficulties which are sufficiently obvious. There is, first of all, the natural reticence to reveal facts of so intimately personal a character. There is the prevailing ignorance and unintelligence which leads to the phenomena being obscure to the subject himself. When the first difficulty has been overcome, and the second is non-existent, there is still a lack of sufficiently strong motive to undertake the record, as well as a failure to realize the value of such records. I have, however, received a large number of such histories, for the most part offered spontaneously with permission to make such further inquiries as I thought desirable. Some of these histories are extremely interesting and instructive. In the present Appendix, and in a corresponding Appendix to the two following volumes of these Studies, I bring forward a varied selection of these narratives. In a few cases, it will be seen, the subjects are, to say the least, on the borderland of the abnormal, but they do not come before us as patients desiring treatment. They are playing their, usually active, sometimes even distinguished, part in the world, which knows nothing of their intimate histories.

HISTORY I.—E. T. (I reproduce this history, written in the third person, as it reached my hands.) T.'s earliest recollections of ideas of a sexual character are vaguely associated with thoughts upon whipping inflicted on companions by their parents, and sometimes upon his own person. About the age of 7 T. occasionally depicted to himself the appearance of the bare nates and genitalia of boys during flagellation. Reflection upon whipping gave rise to slight curious sensations at the base of the abdomen and in the nerves of the sexual system. The sight of a boy being whipped upon the bare nates caused erection before the age of 9. He cannot account for these excitations, as at the time he had not learned the most rudimentary facts of sex. The spectacle of the boy's nudity had no attraction for him, while the beating aroused his indignation against the person who administered it. T. knew a boy and girl of about his own age whose imaginations dwelt somewhat morbidly upon whipping. The three used to talk together about such chastisement, and the little girl liked to read "stories that had whippings in them." None of these children delighted in cruelty; the fascination in the theme of castigation seemed to be in imagining the spectacle of the exposed nates, though actual witnessing of the whipping made them angry at the time.

Accustomed to watch a young sister being bathed, T. had no distinct curiosity concerning the differences in sex until the age of 9. About this time he asked his father where babies came from, and was told to be quiet. When he persisted in the inquiry his father threatened to box his ears. His mother told him subsequently that doctors brought babies to mothers. He credited the story so far as to carefully watch the doctor who came when his mother "was going to have a new baby," in the hope of seeing a bundle in his arm. T. was 9 when he interrogated a servant-girl of 16 about babies and their origin. She laughed and said that one day she would tell him how children came. One Sunday this servant took T. for a country walk and initiated him in sexual intercourse, telling him he was too young to be a father, but that was the way babies were made. The girl took him into a field, saying she would show him how to do something which would make him "feel as though he was in heaven," informing him that she had often done this with young men. She then succeeded in causing erection and instructed him how to act. His feeling at the time was one of disgust; the appearance and odor of the female genitalia repelled him. Afterward, however, he wished to repeat the experience with girls of his own age. Finding the boy unresponsive, the girl took the masculine position and embraced him with great passion. T. can recall the expression of the girl's face, the perspiration on her forehead, and the whispered query whether it pleased him. The embrace lasted for about ten minutes, when the girl said it had "done her good." Later the same day they met a girl cousin of this servant about 10 or 12 years old. The three went to a lonely part of the seashore. The servant there suggested that T. should repeat the act with the little girl. T. was too shy, though the girl seemed quite willing and experienced. The older girl told the younger to keep watch a few yards away, while she again brought about intercourse in the same way. The servant told T. not to tell anyone. Intercourse with the servant was never repeated after that day; from shame he kept the promise for many years.

After this episode T. began to speculate about sexual matters and to observe the coupling of dogs with newly acquired interest. At 10 years he often lay awake, listening to a woman of 25 singing to a piano accompaniment. The woman's voice seemed very beautiful, and so strongly impressed him that he fell in love with her and longed to embrace her sexually. This secret attachment was much more romantic than sensual, though the idea of embracing the woman seemed to T. a natural part of the romance. He was beginning to invest the sex with angelic qualities. The thought of his adventure with the servant no longer caused repulsion, but rather pleasure. He reflected that if he could meet the girl now he could be very fond of her and understand things better. At this time he had not masturbated, nor even heard of the practice. One day, while playing with a girl of his own age, he succeeded in overcoming her shyness and induced her to expose herself, at the same time uncovering his own sexual parts. On this occasion and once afterward he succeeded in penetrating the vulva. Both he and the girl experienced imperfect enjoyment.

At boarding-school, where he was sent at 10, T. learned the vulgar phrases for sexual organs and sexual acts, and acquired the habit of moderate masturbation. Coarse talk and indecent jests about the opposite sex were common amusements of the playroom and dormitories. At first the obscene conversation was very distasteful; later he became more used to it, but thought it strange that sex intimacy should be a subject for ridicule and jest.
