There isn't any specific age. Some Teens just have urge to mutilate when they can't express their feelings of loneliness, being inferior and unwanted. Through self-mutilation, they release their stress and anger. Yes, they may know it isn't the right thing to do. But seriously when things get to some point of time and nobody stands by them, they self-mutilate.
Usually around 7 years but they can live till early teens!
Teens have the highest sex drive out of any age group. As a result, they will want to experiment sexually. It also doesn't help that they are not mentally mature enough to make responsible decisions.
