His first sexual feelings arose around the 12th year; he contends that till that time he knew absolutely nothing about sexual matters. At that age an experience brought his attention to the subject of sex for the first time; he played circus with a younger sister and with his 10-year old uncle and sat on the latter’s back. While imitating a rider’s movements he noticed that his penis became stiff and he had a pleasurable sensation wetting himself in front. He did not know the meaning of this occurrence but was too shy to tell anyone about it. Shortly after that he tried deliberately to reproduce similar situations; whenever he succeeded he also tried to attain ejaculation. He insists that he was not attracted particularly to his uncle, whom alone he had used for this form of gratification, nor to any other boy or man, his only desire at the time was to achieve ejaculation. Later during his high school years, when he had opportunity to gratify himself in the same way, he met a young colleague of his own age, a strong and beautiful boy, who appealed to him very strongly and with that boy playing the passive role he indulged more and more frequently in sexual deeds. In fact as soon as he met that particular boy the thought occurred to him that he would like to have him for the gratification of his sexual feelings in the manner peculiar to himself. During play he used all manner of excuses to climb upon his friend’s back and to imitate a rider’s galloping movements until he had ejaculation. Subsequently he found frequent occasion to use other colleagues in the same way. After drinking it was particularly difficult for him to restrain himself; that is why he frequently had to do with soldiers while intoxicated and one day he was caught and this led to his dismissal from the army. In order to get rid of his unnatural inclination he took up a girl, had normal intercourse with her a few times but without any pleasurable feeling on his part, although in order to accomplish this he had to suppose himself riding a man in the manner customary with him, and eventually he acquired a gonorrheal infection. Then he migrated to South-West Africa, but even there was unable to master his inclination, felt himself impelled to maintain relations with young Hottentots, was caught at it, sentenced to jail, and finally banished from the Country. In this case the gonorrheal infection seems to have put an end to his heterosexual period. * * * * *
