Although I have topped a few times, I much prefer to bottom. I am more attracted to cock than a man's ass. If I want to fuck an ass, my wife is more than willing to oblige. She does not have a cock for me to suck on or take up my ass. She does use a dildo on me fairly frequently. I love cock.
I can’t say I am a cock man, since I have never actually played with one, but I like a nice ass on both men and women. As for cocks, if it shaved along with nice tight balls and cut I love seeing pictures of them
