Another patient, observed by the author, forty-two years of age, married, father of two children, modest and respectable, was arrested one evening for exhibiting virilia sua before girls passing the streets. He used to hang around girls’ schools, following the girls after they used to leave school and attracting their attention ad virilia exposita. At one occasion he ran about in a public park at dusk virilibus expositis. Once when he saw a young woman standing at the window of the opposite house, he immediately exposuit virilia et cœpit se stuprare, standing before his own window so that the young lady was forced to notice him. The anomaly of exhibition is found almost exclusively in men. It is exceedingly rare in women. The girl’s education at home and in school has developed in the woman the sentiment of modesty and chastity in a degree out of all proportion with the same sentiment in men. The woman must be entirely insane before she will expose herself for the sake of lubricity. For this reason the few cases of genital exhibitionism in women, thus far recorded, were all cases of general paralysis. They are found in asylums for the insane where the patient, during a maniacal excitement, tollens interulam medico præterienti concubitum proponit. Still in some women the hyperexcitation of the sexual desire may be of such an intensity that it will lead to exhibitionism in an otherwise normal individual, as the following case of Ungewitter shows: The patient, a servant, twenty years of age, quæ præter amatum suum concumbebat filio matronæ sedecim annos nato sæpissime exponebat muliebria in the presence of boys, eight to ten years of age. In the barn or on porches or even in the open field, tollebat vestes et nudam vulvam pueris monstrabat convertens animos dicendo; “Contemplamini hunc locum! Ea est vulva mea. Jam crines ibi habeo; venite et tangite eam!” She never touched the boys nor did she have any carnal relations with them. The defendant servant was found guilty of attempted offence against morality and was sentenced to two months’ penitentiary. _Homosexuality._—The world is governed by certain fixed laws. This must be admitted even by the mechanistic theory of life. In sexual matters the law of sexual-homologous development is almost as binding as the law of gravitation. The cerebral centre of voluptas corresponds with the sexual glands in the inverse sense. The normal inclination of the individual is directed toward the bearer of the glands of the opposite sex. The male is attracted by the female and vice versa.
