Sex doesn’t feel good.. please help!

My boyfriend and I are long distance and have sex every two months ish, he’s my first but I’m not his first , he cums every time however I feel like there’s something wrong with me because I feel horny before but when it’s happening I don’t physically feel good.

I’m not sure if it’s because I’m consciously thinking about it not feeling how I think it should feel and that I don’t entirely know what turns me on yet , or maybe it’s that I could still be not confident or that it could be the way he’s going down on me as I don’t have anything to compare it to ,I do want to have sex it just doesn’t feel really good,

I’ve never had an orgasm (not even by myself) , Any advice would be great as I feel like something is wrong with me!
