When I was a ballet dancer I was required to wear it while on stage performing and at dress rehearsals. It came off immediately.
Unless you are in the entertainment industry (model, dancer, artist, musician, drag queen) then NO MAN should wear make up. What's more, NO WOMAN should wear make up. It's unnatural, is OBVIOUS as all get out, and makes men/women who wear it looks like crap.
Natural is best. I don't think concealer would fool me into thinking your face isn't a cratered (or whatever defect/flaw you're attempting to hide) mess.
But to each his own. Circus clowns wear make up. And don't get me started on female (and sometimes male) cosmetic surgery where you end up looking like a duck-faced zombie. Joan Rivers (rest in peace) anyone? I get a kick of seeing all the UES women in fancy restaurants trying to eat soup with their huge lips. It's gross.
