The first reason why sex instruction is even more important for girls than it is for boys is because a misstep in a girl has much more disastrous consequences than it has in a boy. The disastrous results of a misstep in a boy are only physical in character; the results of the _same_ misstep in a girl may be physical, moral, social and economic. To speak more plainly. If a boy, through ignorance, rashly indulges in illicit sexual relations, the worst consequence to him may be infection with a venereal disease. But he is not considered immoral, he is not despised, he is not ostracized, he does not lose his social standing in the slightest degree, and when he is cured of his venereal disease he has no difficulty in getting married. He does not even have to conceal his past sexual history from his wife. But if a girl makes a misstep the consequences to her are terrible indeed; it may not only cost her her health and social standing, she may have to pay with her very life. She runs the risk of venereal infection the same as the boy does, but in addition she runs the risk of becoming pregnant, which in our present social system is a catastrophe indeed. To save herself from the disgrace of an illegitimate child she may have an abortion produced; the abortion may have no bad results, but it may, if performed bunglingly, leave her an invalid for life, or it may kill her outright. If she is so unfortunate as to be unable to get anybody to produce an abortion, she gives birth to an illegitimate child, which she is forced in most cases to put away in an institution of some sort where she hopes and prays it may die soon--and, in general, it does. If it does not die, she has for the rest of her life a Damocles' sword hanging over her head, and she is in constant terror lest her sin be found out. She does not permit herself to look for a mate, but if she does get married, the specter of her antematrimonial experience is constantly before her eyes. After years and years of married life, the husband may divorce her if he finds out that she had "sinned" before she knew him. And unless the husband is a broad-minded man and loves her truly and unless she made a clean breast of everything to him before marriage, her life is continuous torture. But even if the girl escaped pregnancy, the mere finding out that she had an illicit experience deprives her of social standing, or makes her a social outcast and entirely destroys or greatly minimizes her chances of ever marrying and establishing a home of her own. She must remain a lonely wanderer to the end of her days. The enormous difference in the results of a misstep in a boy and a girl is clearly seen, and for this reason alone, if for no other, sex instruction is of more importance to the girl than it is to the boy. But there are other important reasons, and one of them is beautifully and truthfully expressed by Byron in his two well-known lines.
