Writers claim that from statistics they have found men are not sexually mature before the twenty-fifth year and women not before the twentieth year. Yet we find them both reeking with sexual diseases before this age. According to Sanger's “History of Prostitution,” it is claimed that three-eighths of the prostitutes enter the life before the twentieth year in New York City. It is safe to say this is a conservative estimate, for the more recent investigations in Chicago and other cities show a very much higher percentage. However, this, together with the statistics of venereal diseases mentioned above, show that it is before the boy and girl are sexually mature that there is the greatest difficulty in directing the impulses and controlling the passions. Chassaignac says that the more healthy and normal an individual is, the better can he not only control his passions, but the less likely is he to be disturbed by continence. Just one more word on the subject of continence, and that is that it is not at all unusual to find men determined to remain continent until they find their ideal woman. Nor for athletes in training engaged in contests, nor for sailors on long sea voyages, and many others for long periods of time is continence impossible; in fact, they are better for it. This knowledge was not lost sight of in ancient times. Reference is made to it in the Bible, in the sending of women prostitutes into the camps of the enemy the night before an expected battle, in order to exhaust or decrease the vitality of the soldiers. When one finds an individual who realizes the force of the sexual impulses and knows how to conserve them, you usually find a person who does not drain or exhaust these forces, but uses them in creative work. Every girl should look upon the man who indulges freely in the sexual relations =without Social responsibility=, as a prostitute far more degraded than the unfortunate girl who is compelled to sell her body to sustain life. Every girl should know something about the physical makeup of a boy as well as of her own, for upon the well-being of both does the future race depend. To be a real mother a woman must understand a boy's emotions and development, if she would sympathize with him. And when she does understand, she will not send him to buy a woman for physical satisfaction. It is this ignorance of parents, together with the silence of the medical profession, which is largely responsible for the terrible spread of venereal diseases which exist today. When a few years ago Dr. Morrow stated that there is more venereal diseases among innocent, virtuous wives, than among prostitutes, this statement should have resounded throughout the walls of every home in the land, instead of which it is kept intact within the covers of large volumes, where only those wearing cap and gown have access to it.
