So... I don’t know what to do

Okay.. so I’m very plus size, venturing into the ssbbw range.. my partner is about 80kgs. & we are obviously having sex.. however we are struggling to find a good position... we want to try me being on top.. but the problem is.. my ass is huge (which is loves so yay..) however his penis bends up & to the left... so if I was to do reverse cowgirl on him.. I would practically have to sit on his chest... & I’m a little nervous that I would hurt him or something... anyone else have this problem...? Or know what to do...
