If a man becomes able to procreate his kind at seventeen but is hardly able to marry before he is thirty he must solve the problem as to what his attitude shall be regarding matters of sex. The earlier this problem is solved the better it is for the young man. Unfortunately, a large proportion of young men do not realize that they have any problem in this field to solve until circumstances, more or less accidental, have already established in them a mental attitude and, perhaps, a habit of life that may not be either wholesome or wise. From what has preceded, it must be evident that from the early months of the period of puberty, through the adolescent and adult period, even until some progress is made in the senile period, every normal male will experience sexual desires. It has been shown that these particular experiences are linked, more or less intimately, with the condition of the sexual apparatus; but whatever the cause, we are confronted with the question, What shall be done about it? When a man experiences a sexual desire does it necessarily follow that the desire must be satisfied? Some have reasoned that the muscles of the arm, if not exercised, wither and become weak, therefore the sexual desires, if not exercised will become weak, and the sexual apparatus, if it does not exercise its function, must become withered and atrophied. While this course of reasoning may seem rational and the conclusion may seem tenable, it is well known to physiologists and sociologists that the reasoning is fallacious; the fallacy rests in the premises. It was assumed above that the activity of the sexual glands was comparable with that of muscles. We must not lose sight of the fact that the male sexual glands are continuously active, and in this continuous activity get their exercise. This activity develops them and keeps them physically perfect after the onset of the period of puberty. Their activity consists very largely in the formation of an internal secretion, the office of which is to develop in the male the highest possible state of virility. Nor must we lose sight of the fact that every procreative act is performed at a sacrifice of some of this vital fluid on the part of the male. A wanton sacrifice of vital fluid either in the act of self abuse or in excessive venery is not justifiable under any consideration; nor may these acts, under any circumstances, be looked upon as sustaining to the gland a relation similar to that which muscular exercise sustains to muscle tissue. In the light of these facts every normal man would admit that frequent masturbation or excessive sexual intercourse, in wedlock or out, should certainly not be recommended as a method of developing the sexual apparatus.
