Sex positions

So I was having sex with my fwb and I'm on top, which is rare. Usually he's in top which I don't mind at all, but this time he wanted me on top and he says get on your feet... and I'm like huh? So I can only imagine he wants me to basically squat and bounce which not only sounds painful but nearly impossible to transition without standing up. So I stand up and he says nvm lay down. Anyone else's dude ask them to i that? And is it possible? Any tips on how to do it?
