imho it's MUCH more complicated than that to THEM physical attraction and confidence are intertwined in a way that's tough for a man to divine, I mean if you're 6'8 and look like Chris Isaak with a beamer yeah most chicks will flip out but for the average guy they do alot of wierd calculus to figure out if they like you whereas guys they're, at least in the beginning, alot more transparent.
That's just mho tho.
