Belly button rings are the only piercings other than the ears that I find extremely attractive on a girl. A belly ring draws attention to the tummy and most girls who have belly rings have nice stomachs. Aside from the obvious tits and ass a nice stomach is always sexy on a hot chick.

Piercings for pain... okay, kinda silly especially when you'd be taking a chance in fucking up perfectly pink nipples. I rather be cained for pain.
