Surely these words from the learned The Science of Eugenics will drive all men to buy a chastity device for themselves.

It is a scientific fact that where boys have been taught the practice of masturbation in their early years, say from eight to fourteen years of age, if they survive at all they often have their powers reduced to a similar condition of a eunuch. They generally however suffer a greater disadvantage. Their health will be more or less injured. In the eunuch the power of sexual intercourse is not entirely lost, but of course there is sterility, and little if any satisfaction, and the same thing may be true of the victim of self-abuse.

Is this the scientific basis of male orgasm denial- – Stop! Masturbating! Now! – Femdom Chastity
