my boyfriend watches porn

when we first started dating we watched a couple videos to learn things bc we both were virgins. i used to watch porn before we started dating but it was very vanilla he did too but his was way more freaky. after awhile i told him i wanted him to delete twitter bc we would be laying in bed he’d be scrolling and get hard and expect me to do something about it and it would hurt my feelings. he deleted the app then i went through his phone a couple months later and he was watching pornhub and some of the stuff was really weird we got into a argument about it and it just got brushed off and i decided i was just gonna stop going through his phone. months later we were cuddling and i saw that he had a notification on his phone from his email saying that someone logged into his twitter account that day and i instantly wanted to cry. i don’t understand why im not enough we have sex everyday he says im good at things and im open to everything we talk about and we try new things i just don’t understand what it is about porn that guys just don’t let go of i haven’t watched porn or even had the desire to sense we started dating. the only person that agreed with how i feel is his mom and she doesn’t know we are going through it but she go into a fight with her boyfriend about the same topic awhile ago so that’s how i know how she feels about it and i feel like i can’t talk to people in my life bc it’s disrespectful to our relationship and him
