Does not this case illustrate clearly the influence of first impressions and the significance of the bisexual foundation in the homosexual attitude? The man is seduced by an elderly man and after that he longs continually to be seduced by an elderly man, in a manner recalling that unforgettable scene. Although capable of heterosexual acts, this side of his nature persists as a sort of compulsory tendency and drives him again into the arms of elderly men to seek that form gratification which was the first he had ever experienced in his life. His heterosexual leanings are repressed. He himself admits that he always saw to it that all such love affairs were nipped in the bud. In other words he is deliberately fighting off all heterosexual stimuli and encouraging the homosexual excitations. Then he arrives at the realisation that he is not like others.... In fact he is bisexual and has the capacity to act as a bisexual being. A careful analysis would have disclosed many interesting features. We wanted only to show how this young man was continually seeking to find his teacher (father?), and what a great deal of neurotic overgrowth stood back of this desire. * * * * * The next case quoted from _Krafft-Ebing_ is also very remarkable: A merchant, 34 years of age, mother neuropathic; at 9 years of age was taught masturbation by a schoolmate; also, homosexual relations with a brother; fellatio; urolagnia; at 14 years of age first love for a school colleague. _At 17 years of age his love ideal changes completely. He is no longer attracted by young, beautiful boys, but by decrepit old men._ _T. traces this back to the fact that he had once overheard his father in the next room uttering pleasurable exclamations after he retired for the night and this excited him tremendously because he thought his father was ... (weil er sich den Vater coitierend dachte)._ Since that time old men carrying on various homosexual deeds play a predominant role in his dream pollutions and during masturbation. But even through the day the sight of an old man is enough to excite him, especially if the man is very old and decrepit when his excitement may be so tremendous as to end in ejaculation. Attempts at intercourse with women in houses of prostitution proved unsuccessful and ordinary men and boys do not rouse him. From the age of 22 years on he carried on a platonic love towards an old gentleman whom he met on the latter’s daily walks. During these walks T. had ejaculation. In order to free himself of this peculiar dependence after several unsuccessful attempts at intercourse with prostitutes _he took along with him a decrepit old man whom he induced to have coitus before his eyes. The scene so excited him that he in turn proved potent. Later on he was able to dispense with the old man’s presence and could carry out the act successfully without that aid. But this improvement did not last long; soon he became impotent once more._
