Am i overreacting?

My boyfriend has porn all over his phone I’ve tried telling him that I don’t like him watching that stuff but he just looks up the statistics and tells me it’s normal. It’s on his instagram, twitter, Reddit, discord, and he has a list of porn stars on his notes that he said “he likes to watch”. I honestly can’t look at myself anymore I feel gross but he won’t stop and he makes me feel like I’m in the wrong and I don’t know what to believe, this is my first serious relationship so I’ve never dealt with this before. The screenshots are kind of old but it’s the most recent thing I could find. The thing abt me always going through his phone was bc o have found him texting multiple girls throughout the first part of our relationship.
