Really does depend on the circumstances. If a beautiful shemale was attached to it, then a deifnite yes. But I've always wondered what it would be like (have fantasised about it a lot), so I guess I would be prepared to experiment and suck anybody's cock just to see what it was like.
Just love the idea of the weight and heat of an erect cock and the pleasant reward of a mouthful of cum at the end.
Think I would swallow, but I won't know til I try it
