Well, I hope he lives up to his reputation if you decide to give him a go around. That kind of sex can be so awesome! And as for disclosure, I think personally I would wait to see if you actually felt the same about a possible relationship. If you don't, why bother expsosing yourself to potential unpleasantness til you are more sure of the people around you when I believe you go there to just let loose and enjoy yourself as you are now and can just stop worrying about the bigger picture for a few hours? I apologize if I'm off base, this is just my thinking on what I would do in your place, but of course I don't know how that place feels.
