I love when guys say girls love it. DUH! They also love shopping, and reading romance novels, and getting manicures. Are you gunna do that too?!?
IMO, girls like it when a guy spends as much time on their appearance as they do b/c it's a bonding mechanism. It acts as a kind of justification for what the girls are doing. Also, IMO, it's a guy's role not to be the "pretty boy" but to be the MAN, not the woman. And then guys wonder why women walk all over them... Sorry, but I do think you're less of a man if you're spending time getting manicures, waxing, and tanning.
I know a lot of girls who subscribe to the "I like a guy who spends a lot of time on his appearance" idea, but it's interesting b/c when I dig a little deeper, quite often they like it but it's not what they're looking for in the man they want to end up with. Some girls say they like a shaved chest, but then really want a guy with a hairy chest. I've had several girls say they don't want a guy who looks as good as them b/c they (the girls) want to be the centre of attention when they're at the mall, the clubs, whatever.
If you're a guy and want chicks, there's two things that will guarantee you want you want. Power and money. 'Nuff said.
