Can’t climax during sex? Advice?

I just... wanna... climax lol, I’ve been having sex with this guy and he’s really good in bed, not going to lie the sex itself feels great and all, but I never cum. Like ever. And I can make myself cum with my vibrator using penetration, but for some reason his penis just isn’t doing the trick :/ I’ve told him about not cumming only once, I don’t think he knows that I don’t cum every time we have sex because I’m a moaner so it all blends together.

He doesn’t do oral sex so that’s out the way, and he fingered me a few times and I’ve been close but then he stops and wants to just go straight into sex (which I have no problems with) but like I said, I would like to climax.
