Sex help

So, my boyfriend and I have been together for a while now and have had sex plenty of times. I just can’t seem to orgasm when we have sex. When he fingers me or does oral, I do orgasm though. Are there any tips or tricks to help me orgasm during sex? I can tell he’s a little let down that he can’t please me as much when we have sex, and I want to be able to orgasm with him.
