He began early to be interested in painting and made special efforts to experience the feeling of love; for the petty adventures with the servant girls did not involve the heart in the least. As he grew all women only appeared to him to be merely objects for the gratification of lust. He had all sort of love affairs but could be true to none for any length of time and did not always reach orgasm with them. He happened to try once the situs inversus and after that he found it always possible to bring about the orgasm. Coitus a posteriori was also a method which enabled him to attain this aim more easily than the normal position. He was already thirty years of age when he saw at a social affair a girl who appeared as a boy in a “living picture.” He felt at once the greatest attraction for her. During the whole evening he kept her in his company, and he felt animated and inspired with the thought that he had found, at last, his soul affinity. A few weeks later he became engaged to her. The picture of her as a boy always floated before his mind. He married soon, experienced tremendous orgasm during coitus and felt himself very happily married. After a few years his potentia began to fail him and this worried him a great deal because he loved his wife tremendously and was ashamed to confess to her the true state of things. He became more frigid and finally his potentia failed him completely. He came into his wife’s room (they had separate rooms) while she was undressing. She was in her tights, the kind in which he had seen her in the role of a boy. At once this roused his passion and he threw himself upon his wife, covering her with kisses, against her protests, for she was very bashful. This happened in day time. His wife had never consented to coitus in day time before. But this time she was taken by surprise and as he pressed her for it, she called out, over and over: “What is the matter with you today!” He did not tell her the reason for his excitement; he was ashamed to request her to dress herself next time in tights. He called to have this remarkable occurrence explained and to be cured of the peculiarity. Later he achieved potentia again but always he had to think of his wife as dressed in trousers. The man was an out-of-town resident and had come to Vienna only for the day. I was unable to find out much about the psychic roots of this condition. He recalled no infantile memories, but thought that the sight of his little sister in bloomers had already roused him. He was much interested in women’s underwear and could have easily turned into a fetichist, one gathering a large assortment of women’s underclothes. I advised him to confide in his wife and ask her for his sake to dress herself in the kind of apparel which appealed to him. That was, after all, a harmless desire which he shared with many other men.
