“I am at the present time 31 years of age, lean yet well built, devoted to male love, therefore unmarried. My relatives were in good health, mentally normal, there were two suicides in our family, on mother’s side. My sexual feelings arose when I was about seven years of age, the sight of the naked abdomen being particularly exciting. I gratified my instinct by allowing my sputum to trickle down the abdomen. When I was eight years old we had in our house a little nurse maid of about thirteen years. I found it very pleasurable to rub my genitals against hers, but there could be no coitus on my part at that time. During the ninth year I went to live among strangers and went to the gymnasium. A colleague showed me his genitals and that filled me with disgust. But in the family where my parents arranged for me to board there was a very beautiful girl who prevailed upon me—I was but little over nine years old at the time—to sleep with her. I found the experience most pleasurable. My penis, though small, was already capable of erection and I had intercourse with her almost daily. This continued for several months. Then my parents transferred me to another gymnasium; I missed the girl very much and during my tenth year I began to masturbate. But the act inspired me only with disgust. I masturbated but moderately, always felt deeply remorseful afterwards, although I could discover no bad consequences.” Here is a man who actually felt disgust at the sight of a friend’s genitals and who found intercourse with women pleasurable. He is excellently on the way to become a heterosexual. At fourteen he falls in love with a school colleague, an experience which every person goes through at about that age, the “normal,” no less than the homosexual. After the final examination (high school) he has intercourse with girls and great pleasure in the act, but he is already making use of some homosexual makeshifts. Soldiers must precede him in the act of using the prostitutes and the thought of having access to a vagina which had just been in contact with another penis, stimulates him. “At the same time I can never kiss women without feeling disgust; _even my relatives I kiss only on the cheek_.” ... _Hinc illæ lacrimæ!_ He protects himself against the sexual excitations emanating from his family circle. His homosexuality is somehow linked to his family. The peculiar action of a boy who allows sputum to trickle down his abdomen, imagining that it is spermatic fluid could probably be traced by means of analysis to a definite childhood trauma. Particularly clear in this case is the heterosexual attitude which under certain influences and inhibitions merges almost imperceptibly into the bisexual and homosexual. * * * * *
