A friend pierced my nipples about 15 years ago with a large safety pin. Well, actually, 1 and 1/2.... We got distracted, and didn't quite finish. I kept it for a few months, but it didn't heal well (imagine that) so I let it heal over. It was the coolest thing. I'm planning on getting them done (both for real this time) professionally in the next few months - weight loss motivation. Totally reccomend.
