@CountryMage I'm sure that people who do that exist, but I seriously doubt they're a non-negligible subset of society, and it's no mystery that deliberately harming yourself can have lasting effects.
@OverlordSaiki no just uneducated, or misinformed, like that College humor video with the butt slapping, some kids get convinced of "proper" masturbating habits, either by a clueless friend, or just trying things that seem to have an effect. If they're lucky they'll just end up with a minor masochistic hobby, but if not, serious injury from trying to have sex with something dangerous ie a shampoo bottle, pool filter/pump....
College boys don't get all horny all the time to the point that they can't think. Aren't spectacled characters supposed to be smart cuz this boy's retarded.
