I know what you mean about DB. He is objectively really good-looking, but the only time I feel any twinge of gut-level attraction is when he's grinning maniacally.

Interestingly, though, I suspect I'd find DB more attractive in real life than JM (although Marsters' personal charisma is supposed to be pretty intense, so maybe not). JM is just such an over-sharing spaz IRL. He'd probably make a great buddy, but I suspect his personality might kill any attraction dead. However, he's a far more interesting and attractive an actor than DB, IMO.
