For me, yeah, looks do play a role. I can't say whether I would fall 'in love' with someone based on looks alone because I cannot say I've ever actually been 'in love'. I can say, however, that most of my relationships (save for two - one in which I'd known my partner for two years before the relationship developed, and one in which my partner pretty much had me wrapped around her little finger) have been started because I found the other person physically attractive. I think the physical attraction did play a large part in how long the relationships lasted... of course, so did the other persons personality but I cannot deny that physical attraction didn't play its role.
