People that look good with piercings would have looked even better without them. They really detract from the natural facial features. Sometimes they even look like moles or zits in their placement!
I don't get the reference that men don't get piercings because they aren't comfortable with their sexuality. If anything piercings get in the way so to speak.
The worst is men with belly button rings! Really?!? That's up there with tramp stamps as highly tacky.
Ear piercings are so popular since they don't detract from the face, and the are on a less sensitive area of the body. These are the only piercings that have the effect of boosting appearance a bit, if the right earrings are selected. And, not gauges either, since those completely alter ear shape and look completely unnatural, thus drawing all attention to them and away from the face. (not in a good way either)
Lastly, it's difficult to land a job as with facial piercings as opposed to someone without them unless you want a job a hot topic or a tattoo shop. I'd rather not :p
