Krafft-Ebing, as might have been expected, refers the phenomenon to functional degeneration, dependent upon neuropathical conditions in the patient, which are mainly derived from hereditary affliction.
He confirms the account reported above from Casper as to the platonic or semi-platonic relations of the Urning with the men he likes, his abhorrence of coition, and his sexual gratification through acts of mutual embracement. The number of Urnings in the world, he says, is far greater than we can form the least conception of from present means of calculation.
At this point he begins to subdivide the subjects of congenital inversion. The first class he constitutes are called by him "Psychical Hermaphrodites." Born with a predominant inclination towards persons of their own sex, they possess rudimentary feelings of a semi-sexual nature for the opposite. These people not unfrequently marry; and Krafft-Ebing supposes that many cases of frigidity in matrimony, unhappy unions, and so forth, are attributable to the peculiar diathesis of the male—or it may be, of the female—in these marriages. They are distinguished from his previous class of "acquired" inversion by the fact that the latter start with instincts for the other sex, which are gradually obliterated; whereas the psychical hermaphrodites commence life with an attraction towards their own sex, which they attempt to overcome by making demands upon their rudimentary normal instincts. Five cases are given of such persons.[32]
In the next place he comes to true homosexual individuals, or Urnings in the strict sense of that phrase. With them there is no rudimentary appetite for the other sex apparent. They present a "grotesque" parallel to normal men and women, inverting or caricaturing natural appetites. The male of this class shrinks from the female, and the female from the male.[33] Each is vehemently attracted from earliest childhood to persons of the same sex. But they, in their turn, have to be subdivided into two sub-species. In the first of these, the sexual life alone is implicate; the persons who compose it do not differ in any marked or external characteristics from the type of their own sex; their habits and outward appearance remain unchanged. With the second sub-species the case is different. Here the character, the mental constitution, the habits, and the occupations of the subject have been altered by his or her predominant sexual inversion; so that a male addicts himself to a woman's work, assumes female clothes, acquires a shriller key of voice, and expresses the inversion of his sexual instinct in every act and gesture of his daily life.
It appears from Krafft-Ebing's recorded cases that the first of these sub-species yields nearly the largest number of individuals. He presents eleven detailed autobiographies of male Urnings, in whom the vita sexualis alone is abnormal, and who are differentiated to common observation from normal men by nothing but the nature of their amorous proclivities. The class includes powerfully developed masculine beings, who are unsexed in no particular except that they possess an inordinate appetite for males, and will not look at females.
As regards the family history of the eleven selected cases, five could show a clear bill of health, some were decidedly bad, a small minority were uncertain.
One of these Urnings, a physician, informed Krafft-Ebing that he had consorted with at least six hundred men of his own stamp; many of them in high positions of respectability. In none had he observed an abnormal formation of the sexual organs; but frequently some approximation to the feminine type of body—hair sparingly distributed[34], tender complexion, and high tone of voice. About ten per cent. eventually adopted love for women. Not ten per cent. exhibited any sign of the habitus muliebris in their occupations, dress, and so forth. A large majority felt like men in their relations to men, and were even inclined toward active pæderasty. From the unmentionable act they were deterred by æsthetical repulsion and fear of the law.
The second of these sub-species embraces the individuals with whom the reader of Carlier is familiar, and whom Ulrichs calls Weiblinge. In their boyhood they exhibited a marked disinclination for the games of their school-fellows, and preferred to consort with girls. They helped their mothers in the household, learned to sew and knit, caught at every opportunity of dressing up in female clothes. Later on, they began to call themselves by names of women, avoided the society of normal comrades, hated sport and physical exercise, were averse to smoking and drinking, could not whistle. Whether they refrained from swearing is not recorded. Many of them developed a taste for music, and prided themselves upon their culture. Eventually, when they became unclassed, they occupied themselves with toilette, scandal, tea, and talk about their lovers—dressed as far as possible in female clothes, painted, perfumed and curled their hair—addressed each other in the feminine gender, adopted pseudonyms of Countess or of Princess, and lived the life of women of a dubious demi-monde.[35]
Yet they remained in their physical configuration males. Unlike the preceding sub-species, they did not feel as men feel towards their sweethearts, but on the contrary like women. They had no impulse toward active pæderasty, no inclination for blooming adolescents. What they wanted was a robust adult; and to him they submitted themselves with self-abandonment. Like all Urnings, they shrank from the act of coition for the most part, and preferred embracements which produced a brief and pleasurable orgasm. But some developed a peculiar liking for the passive act of sodomy or the anomalous act of fellatio.
In this characterisation I have overpassed the limits of the fifteen cases presented by Krafft-Ebing. In order to constitute the type, I have drawn upon one reliable, because sympathetic, source in Ulrichs, and on another reliable, because antipathetic, source in Carlier.
