The strange and almost endless forms of sex-association need not be considered, since they have no moral problem of their own. The man whose sex-force is stirred into energy by the sight of some inanimate physical object is obviously the victim of a sex-repression. And such diseases must be treated as any other repressions should be. These general considerations must suffice here for all forms of sex perversions, such as sadism and its converse. And it is not difficult to distinguish between the unnaturalness of such practices and the natural character of the main sex-types which we have already mentioned. Chapter XI: Sex Education It is becoming evident to all students of the sex-problem that the remedy for many of the difficulties arising therefrom is a wholesome and efficient sex-education. In many cases the parents are not the persons most fitted to give this education. They may not possess the art of imparting knowledge, and often there is a certain reticence between parent and child, which when present creates a bar to the proper handling of this question. The child goes to school to learn, and the school must take its share of this responsibility. Where this is not done the effect is deplorable. In the preparatory school sex has hardly appeared. But in any school where there are older boys or girls, and where sex-education is not given, knowledge is rapidly obtained. Officially sex is ignored until, on rare occasions, it is detected. Severe punishment is then meted out, and perhaps the offender is even expelled, although the school is really penalizing the results of its own system. It is unnecessary to labour the apology that the absence of sex-education ensures innocence. In no school is this the case. If it were, with growing boys and girls, it would be unnatural. Sex-instinct is bound to grow as the physical body grows, and to ignore this fact is to create the conception that sex-instinct is immoral. We then obtain the usual attitude adopted in public schools--that sex is to be indulged behind closed doors and sex literature sniggered at in dark corners. The boy grows up with a totally unclean view of sex. He becomes either an intolerable prude, or else he approaches sex-experience with an entirely twisted conception of sex-morality. One is continually meeting instances of this perverted imagination. Not only boys, but men, will regard an outspoken book on sex, perhaps written with the purest of motives, as "hot stuff," something to be greedily devoured when the eye of respectable authority is conveniently removed. Recently, a man was told that a certain clergyman was a member of a group of students studying sex-psychology. He expressed the opinion, with a knowing leer, that "some parsons are not such fools after all."
