Dancing with a woman is unpleasant to an urning, but to dance with a man, especially one with an attractive form, seems to him the greatest of pleasures. The male urning, in so far as he possesses higher culture, is not opposed to non-sexual intercourse with women, when by mind and refinement they make conversation pleasant. It is only of woman in her sexual _rôle_ that he has a horror. The homo-sexual woman offers the same manifestations, _mutatis mutandis_. In this degree of sexual degeneration, character and occupation correspond with the sex which the individual represents. The sexual perversion remains isolated, but an anomaly of the mental being of the individual which deeply affects the social existence. In accordance with this, many of these individuals, in the sexual act, feel themselves in the _rôle_ which would naturally belong to them in hetero-sexual intercourse. However, transitions to group 3 occur, in as much as sometimes the passive _rôle_ which corresponds with the homo-sexual manner of feeling, is thought of or desired, or at least forms the subject of dreams. Moreover, inclinations for occupations and tendencies of taste are manifested, which do not correspond with the sex of the individual. In many cases, one gets the impression that such symptoms are artificial, the result of educational influences; in other cases, that they represent deeper acquired degenerations of the original anomaly, induced by the perverse sexual activity (masturbation), analogous to the signs of progressive degeneration observed in acquired inversion of the sexual instinct. With regard to the manner of sexual satisfaction, it must be stated that with many male urnings simple embraces are sufficient to induce ejaculation, since they are subject to irritable weakness of the sexual apparatus. In case of sexual hyperæsthesia, and where there is paræsthesia of the moral sense, great pleasure is afforded by intercourse with persons of the lowest condition. On the same basis, desires to commit pederasty (active, of course) and other similar acts occur, though it is but seldom, and apparently only in cases of moral defect, and by reason of libido nimia in individuals especially passionate, that pederasty is indulged in. The sensual desire of mature urnings, _in contradistinction from old and decrepit debauchees, who prefer boys (and indulge in pederasty by preference), seems never to be directed to immature males_. Only for want of better material, and in case of violent passion, does the urning become dangerous to boys. The manner of sexual satisfaction in female urnings may be mutual and passive masturbation. To them coitus is quite as disgusting, wearisome, and inadequate as it is to the male urning. Case 112. The following is an extract from a very circumstantial autobiography which a physician affected with contrary sexual instinct has put at my disposal:—
