LD Boyfriend of 2 years watches porn..

My boyfriend and I are in a sort of long distance relationship, he has the ifunny app and tends to follow all the people who post sexual things basically porn.. Do you think it's ok..? I'm at a stand still and I don't know what to think anymore, I've told him in the beginning that it hurts me when he watches it because it's like he is taking them over me when I'm not around.. And on the other hand- it's long distance so.. I'm trying to hVs the mindset that I'd rather him watch it then get it in person (cheating) you know? Do you think I have anything to worry about? :/
