A left ear piercing has no well-defined or generally accepted significance. There have been urban legends involving the significance of specific ear piercings and homosexuality, but none have proven to be genuine. A specific ear choice is now explained by personal preference.
In the past, it was believed that a man’s choice of which ear to pierce indicated his sexual orientation: the left ear indicated heterosexuality, while the right ear indicated homosexuality. With the surge in popularity of male ear piercings, however, the choice of ear is now based more on personal preference or fashion than on arbitrary rules or urban legends.
