I want to orgasm from penetration!

I really want to orgasm from sex and penetration, but I can only cum from clitoral stimulation. I usually just rub myself when having sex and I can cum, but sometimes I just want to cum without having to do that. I love sex and it feels great and I hate that my guy can’t make me cum from just sex alone. I know most girls need clitoral stimulation and can’t cum from pure penetration, and if I never can that’s fine! But I’m curious if there are any tips and tricks I could try to have a more internal orgasm from just sex with my guy. I get tired rubbing my clit sometimes LOL
