In junior high, a boy got ear pierced. He was teased, made fun of, bullied, and the talk of the school. Not good.
That was in the late 70's.
Miss those days. The place was Orange County California (Conservative part of Cal at the time.)
In some cultures, earring is token of strength for men.
Compared to where and when I grew up, men today are less, less, less masculine (that's becoming a bad word).
The US military doesn't allow males soldiers to wear earrings while in uniform. Well, that's the way it was. Who knows.
The earrings I've seen worn by men are of two extremes: the one, a tiny diamond or something of that sort, looks dainty. The other, those huge loops, looks gross. Ugly.
If you're thinking about getting an earring, on the fence, just remember it will always call attention to itself by many folks. Some will wonder about your sexual preference. That' just how it is. Either way, I am polite and kind to people.
