I think my boyfriend is addicted to porn but I'm not sure. We've been together about 1.5 years. We do have sex but very often he has trouble getting/maintaining an erection. I'm 32 and he's 31.

He says he has a low sex drive but he watches porn and masturbates. He says he can only get aroused once a day, so on days that he's watched porn there's no hope of us being intimate.

We used to have sex about once a week but we don't anymore. Maybe once every 2/3 weeks.

He says he watches porn to relieve stress when he's working from home (1-2 days per week) and also sometimes before he goes to sleep. He says porn has nothing to do with sex.

He's been watching porn since he was a teenager and all through his adult life, even when he has a partner.

I've tried wearing things he likes, giving him as much oral sex as he wants/needs, being more verbal with him (he wants me to says things like "I really want to f*** you) but half the time it doesn't really work. He loses his erection whenever he's focused on giving me pleasure, like touching me or going down on me, which makes me feel horrible.

I've tried to talk to him and have a conversation around how his porn use might be impacting our sex life but he just gets angry and says that porn has nothing to do with sex.
What do you think?
