I’m super upset

I made a post a few weeks ago about how when my boyfriend and I tried to have sex he couldn’t stay hard

He literally couldn’t keep it up

A few hours ago he was horny and he sent me pictures and on his computer screen I saw he was watching porn and he was fully hard

He has no problems when he watches porn but when he’s with me he can’t keep it up

I know I shouldn’t compare myself to other girls or like take it personally but it seriously hurts so much

I have always been insecure, I used to be anorexic and now that I’m not this happens
