Well defined arm muscles, but if they're too muscular, then it's just kind of gross to me.... A nice chest is never bad either.... And of course, I go for the eyes and smile as well.... (this is all men, by the way)

Their hair
<3
I love boys with nice hair
<3
Haha

I love :D

I love long hair, faceal hair and blue eyes and tongue rings

I actually like seeing delicate, musician's (particularly pianists') hands and long eyelashes with both genders.

Probably not all that odd, but I'm a sucker for a shy smile.

For me it would have to be a guy's lower jaw. I'm not sure what you call it. Possibly a "jib". I'm not sure if that is correct. But anyway it has to be square. When I see a guy with a square jaw line I go all mushy and weak in the knees.:sweat:

I like guys with curly hair. Not wavy; curly. Extra points if it's straightened in the front. xD
Which is weird because it bothers me when girls have curly hair.
Also necks and hands. [Why did that statement make me think of strangulation?] Bony hands with tendons sticking out are spiffeh, especially if the hands are cold, too. And necks...? I dunno. I just think they look better certain ways. Eh.

I guess ears, too. Round ears=bad. Gauges are awesome.

This is rather common but I like the eyes and different shapes that guys have.

Hmmn, guys with strong necks are super sexy. Strong or at least gently sloping (gee, how do I put this XD) necks... Or more like, the curve from the jaw and the neck... Like this guy. I also love muscle definition on arms, like a drummer's arms. Not too bulgy or with losts of veins, just, toned. XD

I'm pretty picky with my men. XD For women, I think slender hands are gorgeous. Not manicured or anything, just thing and pretty. XD Long hair is also hot, and I gotta say girls with some tush are also not bad. XDDDDD

I like guys with character in their faces, you know, like something unusual about them... like broken noses and lazy eyes.

Most people think the guys I find attractive are ugly; my husband's one of the few guys I've been with that other people actually find attractive, too, but I still really like his face.
He always has dark circles under his eyes, because he has real trouble sleeping. But most of all, I like his smile. For some reason, he only smiles out of one side of his mouth, so his smiles always look kind of sideways... which is something I've always loved.

i like men with tiny moustache rather than clean look without moustache >w<

Long eyelashes? And for some reason guys who are like dangly skinny in an awkward way, and maybe if they have a sensitive personality?

nice build, either anime style, or more toward perfect greek model...

I like hairy-ness. :]

Beards, bellies. Love it.

I love kind of nerdy, shy smile and a highly attractive man.
Nice Austrailian accents to.

And I just love blonde, tanned beach boys with messy curls.
(With the mentioned nerdy shy smile and an Austrailian accent LOL)
