sex with chubby/husky men

Ok guys so I've been seeing this guy and he's heavy set specially around the stomach area. We've had sex twice but it just wasn't satisfying for myself but I know it was for him. Reverse cowgirl was done both times because regular me on him or him on me just wasn't happening because In all honesty his heaviness/stomach got in the way. Any feedback ladies or ways we can make this work?
