But it is the modern arsenal of _prostitution_ which plays the principal role. The proxenets (pimps) exploit both the sexual appetites of men and the weakness and venality of women. Their chief source of gain consisting in the artificial excitation of the male sexual appetite by all possible means, their art consists in dressing their merchandise, the prostitutes, with attractive refinement, especially when dealing with rich clients who pay well. It is on this soil that are cultivated the most disgusting artifices, intended to excite even the most pathological appetites. Other causes are added to lucre, or are the consequences of it. A boy led to masturbation by pornographic pictures, or by the seduction of a corrupted individual, becomes in his turn the seducer of his comrades. Certain libidinous and unscrupulous women have often persuaded adolescents and schoolboys to sleep with them, thus awakening precocious and unhealthy sexual appetites. Such habits which excite the sexual appetite and cause it to degenerate artificially, develop in their turn a mode of sexual boasting in men, the effects of which are deplorable. To appear manly, the boy thinks he ought to have a cigar in his mouth, even if it makes him sick. In the same way the spirit of imitation leads youth to prostitution. The fear of not doing as the others and especially the terror of ridicule constitute a powerful lever which is abused and exploited. Fearing mockery, a youth is the more easily seduced by bad example the less he is put on guard by parents or true friends. Instead of explaining to him in time, seriously and affectionately, the nature of sexual connection, its effects and dangers, he is abandoned to the chance of the worst seductions. In this way the sexual appetite is not only artificially increased and often directed into unnatural channels, but also leads to the poisoning and ruin of youth by venereal diseases, to say nothing of alcoholism. We have referred especially to educated youth, but the youth of the lower classes are perhaps in a still worse condition, owing to the promiscuity of their life in miserable dwellings. They often witness coitus between their parents, or are themselves trained in evil ways for purposes of exploitation. It is astonishing that the results of such abominable deviation of the sexual appetite are not worse. No doubt excesses disturb the ties of marriage and of the family, and often provoke impotence and other disorders of the sexual functions. It must, however, be admitted that their satellites, the venereal diseases, and their most common companion, alcoholism, are in reality the greatest destroyers of health, and make much more considerable ravages in society than the artificial increase and abnormal deviations of the sexual appetite itself. However, the latter by themselves very often poison the mind and social morality, as we shall have occasion to see.
