I'm a total anal top, have no talent whatsoever for bottoming. It's not in my comfort zone. The man's size is completely irrelevant to me in that regard.

I love sucking cock, though. And although I'm up for any challenge presented, much prefer avg/small uncut dicks in my mouth. My online hook-up profiles actually specify this.

From a mental perspective, being able to dominate a bottom and control the situation is possible with any consenting submissive, but a small-hung submissive scores points for me, just as my larger penis does for him.
