My boyfriend watches porn and follows naked girls on Instagram and I'm not sure how I feel about it

I have been in a relationship for 9 months and we are very happy together (never had a single argument or problems). I love this guy to bits and today I found out that he still watches porn even though we are in a relationship. He also follows A LOT of naked girls on Instagram who look nothing like me.

I am a bothered by both the porn and Instagram girls and I'm not sure if it's normal to feel like that or if it's toxic behaviour? It has upset me but I'm not sure if I should speak to him about it or just let 'boys be boys'. I don't want to be a controlling toxic girlfriend but I also don't want to feel upset.

I have low self esteem (I don't think I'll ever be fully confident in myself to the point where the unrealistic standards of porn and Instagram models don't bother me). It just makes me feel like he's not satisfied with just having me sexually and wants to enjoy other girls too.

Another part of me just thinks that 'I don't blame him for watching porn. Why would anyone be satisfied with me when there are girls on pornhub with perfect bodies and look like models'.

If I were to speak to him about this what should I say? I don't want to come across as controlling and ruin our relationship. Any advice would be appreciated x

Edit: UPDATE!

I spoke to him about it and he was really nice about it. I have decided that I'm going to not set boundaries with porn as we are long distance a lot of the time and I'm just going to try to work on my self esteem more.

I also spoke to him about the Instagram models. All I said was that it "made me feel uncomfortable that he followed so many" and he immediately unfollowed all the revealing ones.

Thank you everyone for all your help in the comments! I really appreciate it and it was helpful for me to see a lot of perspectives on this :)
