It is quite another thing when the invert pays his attentions to minors, or when his appetites are complicated with dangerous sexual paræsthesias, such as sadism. Not long ago the terrible case of a sadist invert, Dippold, startled civilized Europe. By the aid of cruelty and intimidation this wretch martyrized two young boys confided to him for their education to such a degree that one of them died. Legal protection of the two sexes against sexual abuses of all kinds should be extended at least to the age of seventeen or eighteen. Sexual inversion has two curious results which have not received sufficient attention. Human society regards it as quite natural and without danger for individuals of the same sex to bathe, sleep and live together. In lunatic asylums, prisons, reformatories, etc., men are attended to by men, and women by women. The vow of chastity of Catholic priests and nuns leads in the same way to separation of the sexes. In all these customs sexual inversion has not been taken into consideration. It is not surprising, therefore, that homosexuals take advantage of this state of affairs and seek these situations which give them the opportunity for satisfying their perverted passions without running much danger. _They willingly choose a career suitable for their degenerate purposes, and especially that of attendant in lunatic asylums. In the latter case they take advantage of the mental condition of the patients and their incapacity to make complaints. In public baths inverts can freely enjoy the sight of naked men._ So far we have only spoken of complete inversion; but there are transitional stages. Many individuals are neutral, animated by sensations floating between the two sexes. Krafft-Ebing even speaks of psycho-sexual hermaphrodites, who are equally attracted by either sex, and cohabit sometimes with one, sometimes with the other. I knew a married man who was very capable with his wife but in spite of this was unfaithful to her, both with men and with other women. He was convicted several times for pederasty with men and young boys, and confessed to me that he had more pleasure from homosexual intercourse than from normal connection with women, but could satisfy himself either way. An incomplete invert declared to me that his ideal would be a man.
