This statement is of interest because it may well lead us to suppose that the writer, who is of balanced mind and sound judgment, possesses a confirmed homosexual outlook on life. While, however, it is the rule for the permanent direction of the sexual impulse to be decided by the age of 20, that age is too early to permit us to speak positively, especially in a youth whose adolescent undifferentiated or homosexual impulses are fostered by university life. This proved to be! the case with T.D., who, though doubtless possessing a psychically anomalous strain, is yet predominantly masculine. On leaving the university his heterosexuality asserted itself normally. About six years after the earlier statement, he wrote that he had fallen in love. "I am on the eve of marrying a girl of nearly my own age. She has sympathy as well as knowledge in my fields of study; it was thus easier for me to explain my past, and I found that she could not understand the moral objections to homosexual practices. My own opinion always was that the moral objections were very considerable, but might in some cases be overcome. In any case I have entirely lost my sexual attraction toward boys; though I am glad to say that the appreciation of their charm and grace remains. My instincts, therefore, have undergone a considerable change, but the change is not entirely in the direction of normality. The instinct for sodomy in the proper sense of the word used to be unintelligible to me; since the object of attraction has become a woman this instinct is mixed with the normal in my desire. Further, an element which much troubled me, as being most foreign to my ideal feelings, has not quite left me--the indecent and often scatologic curiosity about immature girls. I can only hope that the realization of the normal in marriage may finally kill these painful aberrations. I should add that the practice of masturbation has been abandoned." HISTORY XII.--Aged 24. Father and mother both living; the latter is of a better social standing than the father. He is much attached to his mother, and she gives him some sympathy. He has a brother who is normally attracted to women. He himself has never been attracted to women, and takes no interest in them nor in their society. At the age of 4 he first became conscious of an attraction for older males. From the ages of 11 and 19, at a large grammar-school, he had relationships with about one hundred boys. Needless to add, he considers homosexuality extremely common in schools. It was, however, the Oscar Wilde case which first opened his eyes to the wide prevalence of homosexuality, and he considers that the publicity of that case has done much, if not to increase homosexuality, at all events to make it more conspicuous and outspoken.
