Definitely doggy as well. Unless the top wants to see my front side and face, I usually expect to be treated, and consider myself to be, nothing more than a sleazy hole that tops fuck for unreciprocated sexual pleasure. so being on all fours with my hole positioned up and out for tops to easy access, while having my head down with face covered or looking away from the top is most appropriate.
I also very much enjoy the feel and symbolism of being mounted and held down by a man (froggy style) as he penetrates my asshole. I love Dominant tops so being in a subdued position while getting fucked and taking loads is incredible 😍
