I dont want to have sex

We have been together about 11 months. In the beginning it was great and I loved to have sex with him I got pregnant had a miscarriage and have finally fully healed from everything physically and mentally. I think I have a problem with his past to the point my subconscious wont let me let him into my body. He has had sex with so many girls and I was very insecure when my body was going through everything it was going through because they didnt have to deal with it. Also the fact that he called one of them the prettiest girl in the world (it was about a week before we started dating) so it made me feel like he still wants that he even made an Instagram in 2020 and followed a couple of them.he has unfollowed them after having SEVERAL discussions about the situation. I feel like I just cant anymore. Sometimes i get super horny and imagine things but when it's time to go i cant. I'm not sure if its just him or men period. And I unfortunately lied and said it was just sex period but I dont feel like it is. What should I do? I think I may never want to have sex with him again it's going on two months with nothing and I tried to tonight cause I was horny i told him to clean himself and once he got back it's like the feeling just left my body.

Please help me

I have tried to leave him he doesnt feel it's worth me leaving over. I know it is unfair I'm beating myself up over it enough. Just needed some advice on how to deal with it. I love him and everything else is great but this one thing. I told him about all this and I didnt know his full past I still dont cause I can't handle the stories. But thank you for your two cents.
