Riding, advice needed maybe?

Okay so I’ve rode my person like 3 times, I don’t really enjoy it🤷🏻‍♀️ I don’t feel pleasure like I would if he was doing the work, I kinda just rode him because he seems to enjoy it. When he asked me to ride him backwards I didn’t even know if he was inside of me tbh🤣 I was looking & feeling but heard him say “don’t stop” so I was like oh lmao he is inside of me. It only feels good when it first goes in or if he hits my cervix like he moved himself for like a couple seconds while I was on top & that felt good. I just bounce up & down because that’s what he likes. I also leaned back and started yunno moving myself then he came. Am I doing something wrong?😂 I know some guys (or well I think) don’t really like it when you grind or whatever. What do you ladies do? How big is your partner? (I don’t really think size matters in this but yeah lol) (oh & I ride on my feet)

He’s 6.5 in
