This applies to anyone. Although the reality is that girls have more pressure to look good, I think the guys have a good amount of pressure as well...just not as much as females.

Like, I personally care how I look. I mean I shave, I keep my hair gelled, and I plan to get my teeth whitened after my braces come off. I don't think I'll ever primp myself or anything like that, but I know a good percentage of guys actually care about how they look, they just pretend to shrug it off to look macho. I don't think I'll ever resort to cosmetic surgery(if you think about it, braces are a form of cosmetic "surgery", but eh), but I do like to keep a clean shaven face with good hair and such.
