Boyfriends and porn?

Okay so I send my boyfriend nudes and all but he tells me sometimes that he watches porn. So it only bothers me because like heswatching other girls naked and shit and like idk it kinda maybe bothers me and idk if it should bother me. I know it’s normal to go and satisfy your needs or whatever but when I imagine him going on porn it’s like idk how I should feel about that. Should I be worried should I be cool with it? I told him that it kinda bothers me and he says fine he won’t watch it but low key I know he will anyways despite what I say because at the end of the day the temptation is their but I mean should I be mad that my boyfriend watched porn ? Or am I just overreacting and it’s no big deal?
