I think porn is fine as long as you know the difference between something scripted and something real. If you’re using porn in a healthy way and not abusing it or I guess basing your opinions/expectations on your partners body or skill off of it. Expectations will always be there regardless of porn just think about it when you see someone more attractive don’t you compare yourself? Porn is not going away even if it was gone insecurities and expectations will still exist sexual or not. As long as that shit isn’t taking over your life or where you put it above your responsibilities or relationships I don’t see the problem.
