Insecure

I've always been insecure about my body cuz even in the days I felt very comfortable there were people telling me that I should lose weight. I've been with by bf for almost 2 years and he never made me feel like i need to change myself, that I'm perfect the way I am. But recently I started to get irritated when he would look at some girls on his insta page (even though they're his friends from high school) when they post their bikini pics or sexy pics, or when those meme pages post those pictures or videos with girls that are sexual. I recently snapped at him when he was watching tik toc cuz one of the trends where the girls do the thing where they put their ass in the air to show how it looks like when they go down on someone popped up on his page and all those wap dances, it made me feel insecure about my own body cuz they're all so pretty and I cant help myself but compare myself to them. I apologised to him that I snapped but not how it made me feel. I said to him that he probably liked some of those videos that's why they're popping up on his fyp and he got mad and showed me all the videos he liked on tik toc. I felt bad that I snapped and I started crying and he said his sorry for making me upset. There is this model he follows on all his accounts and he said he does it cuz shes so fit, he likes her pics on insta and tbh it makes me feel like shit and makes me just overthink every and comparing myself to them. He follows a porn star on tik toc. I want to talk about it with him but I don't know how to bring it up, I'm scared.
