What in fact is learned ?

Perhaps if many male youth were not taught (learned) that sensual expression was deviant, and disgusting, borderline criminal... perhaps this is kind of truth (for many) would be far more "normal". Learned behaviour in a culture goes both ways, no doubt that this culture teaches that male youth and their erotic desires is evil, and very abnormal. The balance in all this to me, is that sex is way, way too hysterical and it causes a lot of harm, for it's (the teachings) not honest as a whole. Perhaps the boy in this case is the teacher... Teaching the culture that sexuality is not deviant, maladjusted, or something that is felt only after 17yo?
