When a man wears an earring on his left ear, it is almost always a fashion statement. According to Next Magazine, wearing a single earring is sometimes thought to be a coded message about sexuality, but in this case, it would be on the incorrect ear.
There are persistent claims that in the 1980s, homosexual men in America used to identify each other by wearing an earring on their right ear only. This rumour is impossible to corroborate. Earring have long been fashionable among men of all sexual orientations. If a man wears an earring on only his left ear, it’s most likely because he likes the way it looks.
