Dominating on top

I have no rythym or coordination, like AT ALL. It's so bad that I can't dance, or even clap to the beat of a song. Does anybody have an advice for me being on top in bed? I suck at bouncing up and down because I have awful leg muscles apparently, and no rythym. I can get it for a few seconds if I concentrate really hard but never long enough for it to be pleasing. It's super fustrating, and I hate that my man is always the one doing all the work. It turns me on to be able to please him. I'm good at just sitting on it and sliding back and forth (which feels great for us both) but I wanna learn how to ride better, or ride at all should I say😅
