Boyfriend and porn? Advice ?

Should i mad at my boyfriend watching porn. It puts my self esteem down thinking I’m not good enough. I mean I don’t watch porn which at a point I wish I did in order to make him feel what I feel but it’s not like that. It bothers me a lot but he’s so nice to me and I don’t really want him to stop bc I’m afraid he’s gonna stop admitting he watches it by being scared that he’s failing and lying to me. I still want him to be honest and most girls will be like it’s normal. But it’s normal bc society made it be normal. I don’t care if he was single every man can watch it when their single but he has a gf which is me and it’s like why ?
