IDK, teenagers masturbating a lot isn't only new since porn access has become ubiquitous... Humans can obviously get addicted to all kinds of things and might need help controlling that addiction.

The unrealistic expectations induced by porn have the capacity to negatively impact sex and relationships for generations. Nobody explains to kids that this is acting, that you should have mutual consent on what goes, and choking isn't required. To me that part is the even bigger danger.
