Along with these cases there is a series of homosexuals in whom it is assumed that inversion has been acquired, because they commenced with a normal sexual desire for women. After being seduced by homosexuals, who initiate them in mutual onanism or pederasty, they are suddenly or gradually disgusted with women and become inverts (vide _Suggestion_). In reality, these are only relatively cases of acquired inversion. If we except the cases which depend on pure suggestion of which we shall speak later, there is a latent hereditary disposition to inversion, which is awakened on the first occasion and then develops strongly. It is easy to prove that men with normal sexual instincts immediately abandon the habits of onanism or pederasty which they have contracted through bad example or seduction, or by compensation for the want of the normal object, as soon as they can obtain normal sexual intercourse with one or more women. It is, therefore, false to regard homosexual sensations as depending on vice and depravity: they are a pathological product of abnormal hereditary sexual dispositions. At any rate, this is a general rule which has few exceptions. Sexual inversion is so widespread that in certain countries, for instance Brazil, and even in some European towns, there are brothels with men instead of women. I will mention here a very curious case of purely psychical but complete inversion of the sexual personality, combined with complete sexual anæsthesia: A man, aged 22, the son of an inebriate, with one imbecile sister. Of delicate constitution, but very intelligent, he was possessed since infancy with the idea that he was a girl, although his genital organs were properly formed and were normally developed at puberty. He had a horror of the society of boys, and of all masculine work, while he was quite happy in performing all the household duties of a woman. An irresistible obsession urged him to dress himself as a woman, and neither contempt, ridicule, nor punishment could cure him of it. Attempts to give him employment as a boy in a small town failed completely. His girlish manners made him suspected by the police, who took him for a girl dressed in boy's clothes, and threatened to arrest him. When he was compelled to put on male attire he consoled himself with wearing a woman's chemise and corset underneath. I carefully examined this individual and found him affected with complete sexual anæsthesia. He had a horror of everything connected with the sexual appetite, but the idea of sexual intercourse with men was still more repugnant than that of normal coitus with women. Although the testicles and penis appeared absolutely normal, he never had erections. His voice was high pitched and his whole manner suggested that of a eunuch.
