[BK] Such pamphlets as “What a young boy ought to know” or “What a young girl ought to know” show a touching naïveté. Young boys and girls, if of the age to understand such pamphlets, do not need to know anything, for the simple reason that they know everything, and in a more prurient way than their elders. It is the height of absurdity to give lectures on sex problems before classes in high schools or colleges, where a large percentage of the boys have already passed through all the stages of gonorrhoeal infection and a good many of the girls are addicted to the practice of autoeroticism. After such habits have been acquired, lectures will be of no avail. Nor are books, fit to be given into the hands of boys or girls, of any value. By the time a child is able to understand such books it knows more of sex than the book can teach. [BL] It is questionable if physicians always appreciate the dangers of venereal diseases and of sexual irregularities. It may sound queer, but the author has met with many physicians who think no more of gonorrhoea than of a cold in the head, and who consider a chancre a huge joke. Such physicians—and their number is legion—have never acquired any proper knowledge of sex. [BM] It is only the covering that gives to any part of the human anatomy a certain element of the obscene. The female arms are certainly more beautiful than the female legs. Still the bare feminine arms, because they are constantly seen everywhere, are seldom noticed by any healthy male; but let a woman bare her legs in public and she will shock the entire community by the strange, unusual sight. [BN] The following lessons for boys and girls at the period of puberty should be given only if preceded by preventive measures during infancy and early childhood and by lessons in propagation of plants and of animals. If the children have never been instructed before, and there is the least suspicion that they have already tasted from the tree of knowledge, either in the form of masturbation or in that of illicit venery, such lessons are not only of no value, but they may even do more harm than good. The descriptions of the sequelae of masturbation and of venereal diseases may make the young people desperate and not seldom cause suicide or wanton recklessness. [BO] In the girl a certain kind of nocturnal ejaculation also takes place, manifested by an abundant discharge from the Bartholinian glands and the expulsion of Kristeller’s slimy plug from the cervix. These phenomena during sleep are usually of a vague kind in young girls and are seldom impressed upon their consciousness. The real pollution that awakens the sleeper and leaves its traces in the individual’s memory occurs usually only in boys, and in the female sex only, after a perfect orgasm has been experienced in the state of wakening.
