In general, no girl of today should marry before she is twenty-five. She can safely wait until she is thirty. By the time she is twenty-five, she has reached a maturity of judgment that will allow her to choose a permanent mate with whatever wisdom she can bring to bear upon the subject. By that time, she is able to find men several years older than herself more companionable, and this is as it should be. The young girl, while she may have occasional “crushes” on older men, seeks her friends and companions from among the boys who are of her own age. Her regard for older men is more hero-worship than real affection. This would lead her, if she chose a mate during these formative years, to pick one from among the boys of her own age. And this is wrong. Men age much less rapidly than women. Women are older by intuition and psychology than men. Theirs is the burden of the future of the race, which may account for their more adult attitude. So that, if a couple marry when they are nineteen or twenty, and are the same age, ten years later the woman will be much more mature in her outlook on life than the man of the same age. Here is where the first seeds of discord are sown. Whereas, if the girl waits until she is twenty-five, she has had time to realize this fact, and has already altered her ideas concerning men, and chooses for her friends men who are three, four, or even ten years older than herself. A girl of twenty-five marrying a man of thirty stands a much better chance of achieving permanent happiness than a girl of the same age marrying a man of equal years. Self-control during adolescence can be acquired without any unpleasant effects, and without seeming a burden upon the young people. A whole-hearted indulgence in all types of athletic exercise goes a long way toward draining off the erotic energy crying elsewhere for direct liberation. A devotion to any branch of learning, a hobby of any kind, acquaintance with the world of nature, all these keep the mind in safer channels. On the other hand, the way to stimulate these undesirable emotions is attendance at suggestive shows, reading licentious books, and indulging in giggled conversations with other girls upon the subject of sex. The current tendency for young girls toward drinking is also bad, since it stimulates the erotic energy. The wise young girl will avoid all this, not prudishly, but calmly and intelligently, until she has stored her body with the wealth of physical strength and her mind with the wealth of counter-irritating knowledge. The average young girl does most of these things because she fears the ridicule of her companions if she refuses. Her answer can be simple. If she calmly points out that she knows all of the decent facts about sex, and therefore does not need the insinuated half-knowledge that pornographic plays and books give, she will gain the respect, not the mockery, of her friends.
