Orgasm Help

Hi! So my boyfriend and I are very sexually actively but out of all the times we’ve had sex, I’ve only had 2 orgasms. I honestly still love every time we’ve had sex (even if I don’t cum). But does anyone have tips on things I can try? We’ve tried including vibrators and doing different positions… I’m still having trouble and it makes my boyfriend feel really bad. I think I’m too in my head. Any advice??

PS… I have no luck with cowgirl because it kills my hips (side note: I have terrible hips) How do I make cowgirl more enjoyable?

Thank you in advance!!!!
