Good-looking or handsome. Though, I prefer to use my language (Spanish) to refer the men's beauty. =P

Beautiful is for gay people who has topless pictures on his profile like ^ cough :)

Beutiful is if this man is homossexual. Handsome if he is a really man. =)

I think mostly handsome are for men and Beautiful are mostly used for women

in my opinion, it totally depends on how the man looks like. He may have effeminate features that one would only find on a woman's face. its possible that the guy's facial features are so delicate to the point of him looking more like a girl than a man. believe it or not some girls actually find these kind of men attractive. When i hear girls saying " that guy looks beautiful" , i would think that the person has an aristocratic physiognomy like that of roman or Parisian blue bloods.
