My understanding is that it’s not necessarily porn addiction that causes this, but a particular style of masturbation that some people refer to as “death grip”. Source: a friend of mine who used to masturbate every night before bed to sleep better, but this began causing issues with his partner due to ED. He eventually solved it by using a different grip while masturbating.

In short, if you feel like you’ve come away from this conversation with things to reflect on, then that’s great and I’m glad about that. However, “porn addiction”, as a term, describes a whole bundle of stuff that is still pretty poorly understood, because it can be hard to discern between symptoms and causes
