I don't like earrings on men, especially men over 30. I mean, as much as I love Harrison Ford, I wish he would take that flipping earring out - it looks so naff!
Urrggh I hate them, they look okayish as teens or in your early 20's but as Maria said once you get to a certain age they just look naff. I wouldn't want my BF to get it done.
It really does suit some guys. My brother used to wear studs in both ears - he got away with it because it really did suit him. He only wears one stud these days though.
