Men who have trouble cumming from intercourse, what is one thing a girl can do to make it happen?

Long story short, My new partner has always had trouble cumming during intercourse. I understand this because I am a girl who cannot cum from intercourse. And I’m also a bit inexperienced to begin with. I am not going in with an expectation, I just want to try some things out for the both of us. Anything a girl has done for you that made it happen? Any specific spots, motions?
