In at least 24, probably many more, of my male cases there is a marked contrast, and in a still larger number a less-marked contrast, between the subject and the individuals he is attracted to; either he is of somewhat feminine and sensitive nature, and admires more simple and virile natures, or he is fairly vigorous and admires boys who are often of lower social class. Inverted women also are attracted to more clinging feminine persons.[203] A sexual attraction for boys is, no doubt, as Moll points out, that form of inversion which comes nearest to normal sexuality, for the subject of it usually approaches nearer to the average man in physical and mental disposition. The reason of this is obvious: boys resemble women, and therefore it requires a less profound organic twist to become sexually attracted to them. Anyone who has watched private theatricals in boys’ schools will have observed how easy it is for boys to personate women successfully, and it is well known that until the middle of the seventeenth century women’s parts on the stage were always taken by boys, whether or not with injury to their own or other people’s morals.[204] It is also worthy of note that in Greece, where homosexuality flourished so extensively, and apparently with so little accompaniment of neurotic degeneration, it was often held that only boys under 18 should be loved; so that the love of boys merged into love of women. About 18 of my cases are most strongly attracted to youths,—preferably of about the age of 18 to 20,—and they are, for the most part, among the more normal and healthy of the cases. A preference for older men, or else a considerable degree of indifference to age alone, is more common, and perhaps indicates a deeper degree of perversion.
