what i like to see on guys? :kukukuh:
these are what i tend to look for/at :
for physique, preferably taller than me or the same height, but the weight is none to extreme. like, extremely skinny or extremely big is a no-no for me. i like chubby-ish guys, but thin guys are nice to look at too. heck, i even like androgynous-looking guys (and androgynous girls, but let's not get to that ;P)
i think hairstyles/color depends on the guy himself, but long hair doesn't usually suit guys (1. they don't maintain it well, 2. doesn't suit their face shape), tho it does for some. as for eye color... well i prefer guys with light-colored eyes (blue, brown, green, gray, whatever).. because i'm used to seeing ppl with dark eyes (being an asian and living in asia for most of my life). it's refreshing to see various colors ^_^
however, the first thing you see when you look at the person is the overall appearance, eg. 'handsomeness'+'cleanliness' etc etc. my taste is pretty varied, almost extreme, even, for some. i like gothic-ish guys, withdark attire, piercings, eyeliners and whatnot, and yet i like looking at guys who look like the studious type/nerdy. sometimes the clothes can enhance a person's body, or really make you look weird. of course comfort should be the most important factor to choose what you wear, but a little dash of style magic can work wonders on your confidence =)
oh, and this is quite my own personal thing, but i like to look at guys' hands. and smile. and speccies.

hehehehehe ok, TMI ;P
but in the end, like takeya says, it's the personality that counts. appearances wither over time, but personality can live out till you die. like my mom keeps reminding me, "let your eyes hurt a little as long as your heart doesn't".. or something along those lines. heheheheh.
