No idea, but many years ago, in the UK, when I was on a trolley being wheeled to the operating theatre, one of the nurses spotted that I had an earing and a stud, in each ear. They had to hurriedly tape them up, before I was in the theatre.
The Nurse asked me if I was gay, because of the earrings. "I'm having a vasectomy" I said, "what do you think"?
