How to be okay with your boyfriend watching porn?

Hey guys! The questions in the title really lol. Logically, I KNOW i shouldnt care and that everyone does it. But i cant help but feel insecure.

He tells me he doesnt watch it, but went on my boyfriends instagram a while ago (with him beside me with his permission!!!) and saw a pornstar in his history, so obviously he does. (He doesnt know i saw this as i dont want to seem like i care, because i dont want to care).

And like i said i believe it’s normal and okay, but it does make me feel insecure about my body as these women are perfect ect.

Has anyone else struggled with this and has any tips to overcome it? Hope this makes sense! Thanks in advance ☺️❤️
