When youre having sex, do you have to rub your clit right before you cum? Advice needed :(

Ive only been able to cum during sex like 3 times out of all the times ive ever had sex and i was masturbating right before. I want to be able to have an orgasm every single time. How can i do this? Do i have to rub my clit before and during? Do i have to do it while im cumming? Because if i stop, yes my boyfriend feels great but i feel like i lose my build up :/

& i have no problem cumming quick by myself or while being eaten out. I just want to do it during sex with his dick inside me!
