So I’ve always been able to make myself orgasm, but when I’m with a guy I can never fully get there?

It’s like I get to the point where I would usually cum but nothing happens, whatever they are doing feels really great and I still enjoy it but instead of climaxing I just get the urge to push?

It’s like cumming but without the good tingly bit I get when I do it myself 😂 Does anybody else know what I’m talking about? Or what the cause might be??
