The point he is making is that children are too fucking stupid to delve into something as emotional as sex. Hell, most adults aren't even emotionally mature enough for sex, which is prob why current american culture views sex as just another thing like basketball or shopping. It's one thing to be accepting of your body and others, and to share yourself with people you actually love - it's another to fuck without thinking about anything other than "omg da feels so guud nar lawl".
