I would suggest that little boys play with little boys, and that little girls play with little girls. This not to say that little boys should never play with little girls, and that little girls should never play with little boys. It is to say that by far the majority of a child's playing should be with his own sex. So much of the sex drive is caused by the unknown. If a little boy plays with other little boys, there will be a mystique about girls, but if he plays with little girls too much, they will become commonplace and there will be a mystique toward little boys. The human race is so constructed that when something becomes commonplace, it is not nearly as attractive to us. The old adage, "The grass is greener on the other side of the fence," applies here. In childhood this grass on the other side of the fence should be the opposite sex. If it is one's own sex, there would be a curiosity about that. Now I'm aware that the modern psychologists will say, "Let little boys see little girls, and let little girls see little boys, and let them become acquainted with the biological differences, and let them see each other unclothed." Let me remind you that that same generation of modern psychologists is turning out an unbelievable amount of homosexuals in our country!
