Boyfriend looking at Porn

Leyaloni

So I’ve searched my boyfriends phone and I see that he follows and likes lots of Porn accounts on instagram and Twitter. Or pornstar accounts with girls shaking their asses or posing with legs spread ect... Him and his best friend send posts of these girls back and forth to each other saying “isn’t she hot?” Or “Cute?”. I find it really insulting that he would do that. It makes me feel inadequate or not good enough. We’ve been together for two years now. I feel like if your in a relationship you shouldn’t be doing that, but idk if Im being crazy. How do you guys feel? Are you okay with your boyfriends doing that? Should I be okay with him doing that? Or should I legitimately be mad?
