Tips on Reverse Cowgirl?

Iv had sex many many times but have never actually done reverse cowgirl 😩 for some reason i feel like im gonna be bad at it or i feel like my ass isnt big enough to do that or idk. Iv done cowgirl plenty of times and have been told im good at it. Iv turned around and did reverse for like 4 seconds but idk. Is it the same motion as regular cowgirl? How should i go about it? And do guys think that position is sexy?
