Since the responses are supposed to only be from straight guys I can say that when I was straight I really liked it when she was on top and going for a ride.
My girl is more submissive than dominant most of the time, but she does "pull rank" (it's all about her) at times. I love it when she straddles my lap as I'm sitting, and rides me while I hold her sweet tender ass with both hands (when I'm not fondling her tits and nipples). So my choice would be A. Ride me.
Best to try everything on for size to see what fits but I’ll defiantly be spanking that ass from behind
My usual would be to give you oral until you climax. Then we go around the world. Slide up into missionary. Lift your legs up with your ankles on my shoulders. Take your right ankle and cross it over to your left and straddle your left leg and continue plowing you on your side. Then pull your hips up into doggy. If it takes a while (which it often does) maybe a little prone bone. I'll pull it out and finish on your ass or back.
Ride em cowboy! You pretty much went though everything I was thinking. Especially the legs up on my shoulders so it can be real deep.
