I really appreciate it when a guy I like takes care of himself and stays fit. I don't know about six packs though. Honestly I don't differentiate much between a guy who has a six pack and a guy who just has a flat stomach. I wouldn't call it a bonus though, and I think if it came down to something like that I would prefer normal abs to a six pack. It's just a lot smoother and nicer looking, makes me want to lick and kiss! And in my personal opinion I always thought six packs are kinda strange and a little gross looking.
