After further, continuously progressive analysis the subject himself came to the conclusion that he must have been struggling against homosexuality. Now he understood his sudden decision to get married, after having maintained right along that he would remain a bachelor. He was interested at the time in a laboratory assistant, a young man with pretty rosy cheeks. He showered gifts upon that young man and planned to give him an education so as to have a friend always close to him. The first compulsory acts appeared at the time. He married, felt unhappy for a time but for a few years he lived at least a relatively quiet life. Then another man came into his life destroying his peace of mind, a man who had lived for some time in foreign countries and now returned to his fatherland. This was an uncle. Now he recalls something of which he had not thought for many years—for he was going to keep this from me,—namely, that he had maintained certain intimacy with this uncle for about a year. They lived in a boarding house where they occupied a room together. The uncle always came to lie in his bed and they played with each other before falling asleep. His uncle carried out the kind of manipulations which he now required of his women lovers: manual gratification. During his relations with his wife, however, he wanted to avoid all thought of homosexuality; she should not practice this form of gratification for him nor should her body remind him of homosexuality. She must save him of the burden of homosexuality which still plagued him under the form of onanism. After resurrecting this memory a mass of other homosexual data came trooping forth out of his past. This man was strongly bisexual from childhood with particular predisposition towards the male sex. As a child he did crocheting and showed various female characteristics. After the onset of puberty his homosexuality was strongly repressed, persisting chiefly under the guise of onanism. For the act of masturbation takes place just before falling asleep in a half dreamy state during which he thinks, though indistinctly, of his uncle and of other men. The latent homosexuality was the most important factor in his neurosis. The result of the analysis was most gratifying in this case. The subject soon abandoned his compulsory acts and was able to sleep quietly. His life became regular; he ceased being a Don Juan. He allowed his wife to carry out those manipulations which seemed essential for his orgasm and for his peace of mind. Occasionally I see him. These observations show that in the dynamics of the “polygamic neurosis,” homosexuality plays a tremendous role. The observation that every love is really self-love receives new confirmation. Don Juan seeks himself in woman and finds in her that femininity which has turned him into a Don Juan. * * * * *
