I wonder, too, merlen.
I think most of us have some sort of preference, but as dlish said, he'd probably allow himself to be seduced by one who wasn't his type. Although my guess is that he isn't alone, I challenge you, dlish, to overcome your shallowness.
Can you truthfully say you'd screw someone who wasn't your type (again, via seduction), but wouldn't bother to get to know her? Or is it that you wouldn't want to be seen with her?
Packin' my bags ...
