The right ear or gay ear is the ear that most homosexuals tend to get pierced more often than the left ear, hence when somebody who is heterosexual is getting their right ear pierced he is getting the gay ear pierced. Straight men should avoid getting this ear pierced if they wish to carry onward their straightness.
