This shows what a moral lesson may do even for him who grew up to manhood without any sex-instruction. The young man who has the desire not to be dominated or controlled by sensual passions and propensities, requires settled principles, a firm purpose, and a strong will. But if the training of his will-power has begun from early childhood, thus effecting the needed self-discipline, and if disgust against everything vulgar, as the company of lax women, has been implanted in his heart, he will find the means to get out of the way of vice and to avoid the contamination by venal sensuality. The best means of vast importance as occupying and consuming the sexual powers in a substitute form are bodily and mental labors. These labors, as a rule, are lulling to sleep sensuality. If the control of the sex-reflexes is not cultivated, if the training of the will is ignored, meretricious venery will surely take hold of him and infect him, it being only a matter of time when it happens. The young man will exercise continence if he has been taught from early childhood that his sensual yearnings must be restrained like his propensity to overeat, to overdrink or to overexercise. Because a young man wants a thing it is not necessarily good for him to have it. Man has little right to satisfy his desire by unchastity, says Ellen Key, as he has to satisfy hunger by theft.[ER] If the young man has learned in time the responsibility and duty of the man towards the woman, if he has been made aware of the fact that one false step ruins the girl irremediably for her entire life, if his attention has been called upon the serious consequences for the woman, such as pregnancy, motherhood and social ostracism, he will not so easily ever try to seduce an innocent girl. He will treat every woman he meets with in life as he wishes his own sister or future wife to be treated by others.
