Lol, first of all, I'm not going to talk to a girl if I don't find her attractive in some respect. A nice smile, kempt hair... Has a nice scent? I'm also the kind of guy who likes to surround himself with women who have nice asses and legs. Soccer players and Tennis players, mostly. :D
I think it's silly to avoid thinking women are attractive, and I think it's equally shallow to disregard the appearance we can see with our own eyes for the personality that is often a beguiling shell of who they really are deep down. "Deep conversation" probably isn't that deep. It's something people tell themselves when they want to be content with a conversation about partially fleshed opinions.
After I meet an attractive girl, it is her mannerisms and aura of stability and contentness that make me form a crush.
Is it befitting that someone like me met his current girlfriend of two years online, and that I fell in love with her through AIM, not even know what she looked like until she moved right down the street from me? :p
