Has it actually? I know phrases like "porn addiction" are casually used, but the last time I looked there wasn't much study of it in terms of the science of addiction. Most of the people self-reporting porn addiction were experiencing distress because of the incompatibility of their porn use with their religious beliefs, but their use itself wasn't extreme or pathological per se.

Which doesn't mean there aren't problems with it, or that it can't cause extreme problems for some people. But in my exposure to addiction medicine, it's treated more as a psychosocial compulsion like shopping or video game addiction.

There's a lot of misleading or outright misinformation about the effects of pornography. For instance one study claiming an incredibly high rate of abuse depicted in pornography categorized ejaculating on someone's face as abuse. It's also very hard to research because it's difficult to establish controls: almost all men watch pornography.
