human male becomes
sexually perfect, varies from ten to fifteen years. In the United
States puberty in the male usually occurs at the age of fourteen and a
half years. In tropical climates it occurs at nine or ten, and in cold
countries, such as Norway and Siberia, it may not take place until
eighteen or nineteen. Vigorous physical exercise tends to delay
puberty, anything exciting the emotions tends to hasten it.
Stimulating foods, pepper, vinegar, mustard, spices, tea and coffee,
excess meat nutriment hasten puberty. A cool, unstimulating vegetable
and farinaceous diet may delay the development of the sexual system
several months or a year.

THE SIGNS AND CHANGES OF PUBERTY

In the boy the signs of puberty are the growth of hair on the skin
covering the pubes and in the armpits. Chest and arms broaden, the
frame grows more angular, the masculine proportions more pronounced.
The vocal cords grow longer and lower the pitch of the voice. Hair
grows on chin, upper lip, cheeks, and often on the body surface.

THE SEXUAL MORAL LAW

The sexual moral law is the same for both sexes, and equally binding.
It may be summed up as follows: "Your sexual urges, instincts and
desires should never consciously injure an individual human being or
mankind in general. They should be exercised to further the value and
happiness of both."

THE MALE ADOLESCENT AND CONTINENCE

The perfect carrying out of this general moral law implies continence
on the part of the male adolescent until marriage. Continence is
positive restraint under all circumstances. Strict continence is
neither injurious to health, nor does it produce impotence. While
self-denial is difficult, since the promptings of nature often seem
imperious, it is not impossible. It is certain that no youth will
suffer, physically, by remaining sexually pure. The demands which
occur during adolescence are mainly abnormal, due to the excitements
of an overstimulating diet, pornographic literature and art, and the
temptations of impure association.

WHY YOUNG MEN GO WRONG

Foul thoughts, once they enter the mind, corrode it. The sensual
glance, the bawdy laugh, the ribald jest, the smutty story, the
obscene song may be met with on street corner, in the car, train,
hotel lobby, lecture hall and workshop. Mental unchastity ends in
physical unchastity. The habit common to most adolescent
