How can I fuck my gf harder?

You could try giving her non-vaginal orgasms. Learning how to eat pussy really well is a good skill to have.

Just gotta keep experimenting anon.

My lover likes it deep as possible and we've experimented with many positions to find the few that could satisfy her quickly and easily.

Might want to try giving her oral sex, fingering, or using toys as well.

OK OP, here's what you do.

When she's on her back you have to angle your penis upward. Sort of push against her vagina so that you feel it against the top and inside of her vagina. This way it'll start hitting her g-spot.

When I was with my old girlfriend I would do that and I didn't even need to do it hard necessarily, just consistently. So in your case you'll want to just take it slow, but forceful enough to push against the upper wall of her vagina. Guaranteed moaning or screaming if it's done right.

Minimal energy, maximum pleasure

Non-vaginal orgasms are not a problem, the thing is she enjoys much more when my penis stimulates her in the inside. I have to do it really fast to make her climax but it's so physically demanding with her!
Also my penis is always pointing upwards, so it seems that this is not a problem.
