Being a rarer guy who only came from prone masturbation (or PIV), I would take my time with my partner but if I kept it short .... it would be to then use my cock for a while. One of the side effects of prone masturbators was they take a long time to orgasm from PIV.
I would go at it a while and if she came (super) I win, if she didn't that was ok ... I would pull out and go back down.
Find what works for you as a guy, learn, grow, and talk to your partners and do.
If I cared for a woman and we hadn't been going out for long ... I would usually "mouth" I love you and her first name with my tongue on her clit.
I would then smile on the inside.
