Can’t Orgasm

So my boi and I have been doing the dirty for a few weeks now, he’s slept with people before, and he’s my first. So when he fingers me it’s amazing, but I never orgasm. When we have sex, I don’t enjoy it as much but I try to make it seem like I do, for his benefit, because he gets upset when he can’t pleasure me. I really want to enjoy sex, and I know it would be better if he stimulated my clit while going in, but I don’t want to seem bossy or demanding.
