“No intercourse; presumably would be impotent with woman.” “Intercourse previously pleasurable; sudden disappearance of feeling now makes intercourse impossible.” Another writes laconically: “bisexual.” At least one-fourth of my overt homosexuals are really bisexual with subsequent modifications of their bisexuality brought about through causes which will be discussed in a subsequent chapter of this work.[33] We now turn our attention to the next case. It shows clearly that heterosexual tendencies arise in the homosexual under the influence of alcohol and it also proves that under the pressure of danger the homosexual craving by drawing on the greater libido turns into the heterosexual channel: D. S., a clerk, 35 years of age, has been homosexual for the past fifteen years. His father died when he was 7 years of age. He hardly remembers his father. His mother was always very severe, and very energetic as well as exceedingly nervous,—she had to go frequently to sanitaria to recuperate. He admits having had feelings predominatingly homosexual ever since childhood. He interested himself only in boys and his mother brought him up in girlish ways. He began masturbating at an early age and already at the age of 12 he carried on mutual pederasty with his comrades. At 17 years of age he attempted intercourse with girls. That was not easy, his _potentia_ had to be roused by them first through manual stimulation, then he felt some pleasure, which was curbed partly because he could not help thinking of the possible danger of venereal disease, of which he had seen some illustrations in a museum of wax figures. He was also thinking about his mother reflecting, what would she say if she knew what he was doing! From that time on and until he was about 21 years of age he had intercourse with women regularly about every month. Then he fell in love with his office chief, who was an extraordinarily attractive man. (He gives a romantic description of his first ideal. This account, of course, is not trustworthy. In fact the photo of his latest ideal, also praised by him as an Adonis, shows the stolid, expressionless, rather common face of a very ordinary man, a soldier in the artillery branch of the army).
