What is the prettiest GUY you've seen from an anime?

Nagihiko is so pretty.

Kinoshita Hide-kun from Baka to Test to Shokanjuu no doubt!

iwaki-san <3 he's beautiful

Kiechi

Ryuuki Shi, from Saiunkoku Monogatari -he is bishie/bishounen, but I do not consider him "girlie" - I think he is extremely good-looking.

I guess Yuki.
He was a woman in his past life so I guess it makes sense :)

Of the guys not actually dressed in drag, I'd have to say Emperor Shi Ryuuki from The Story of Saiunkoku.

Aoi from Maid Sama

Fisheye from Sailor Moon

Otoya Ittoki, Shou Kursu, Masato Hijirikawa, Tokiya Ichinose, Natsuki Shinomiya, and (my love) Ren Jinguuji.
From Uta no Prince-sama

or

Mikoto, Toru and Yuujiro
From Princess Princess

or

Chiga
From Saito Kaichi ni Chuukoku

I always though Gai from Guilty Crown was pretty, he has pretty eyes and pretty hair
