Can't have an orgasm with my bf 😢

So I have this problem of not being able to have an orgasm during sexy times with my boyfriend. He is my very first so I am not quite sure what it's supposed to feel like to have an orgasm during sex. he is experienced already so he knows what he's doing and it sure feels like it. I can get off by myself (which only feels "meh" tbh) but whenever it's with him, doesn't matter if penetration or if he's stimulating my clit, it just "won't go over the top". I read that it might help if I would touch myself at the same time but I don't really like touching myself so that adds another problem 😔 he is starting to feel disappointed in himself, and I tell him it's alright. I don't need to orgasm to enjoy it. But it still kind of puts a little pressure on me. Would just be lovely to experience it as well 😊
