Depends on if you want to look homosexual or not.
Earrings aren't exclusive to females. For example, piercing the ears of male and female children is a tradition observed by some Hindus, and is still a prevalent ceremony performed in the Indian villages that have not been exposed to Western influences. Piercings can look sexy as Hell on some guys too. Have you seen those Korean entertainers? They're living proof that piercings don't automatically make guys look effeminate. Anyway, if someone chooses to cultivate an androgynous or feminine appearance, that's their form of self-expression and there's nothing wrong with that.
