well I have pierced ears, a huge tattoo and my navel pierced. I had the navel pierced when I decided to go into bodybuilding with the thought of competing one day. I can tell you this about it...I sat for 9 hours having my right hip tattooed and ate lunch during it no problemo. I had my navel pierced and fainted immediately afterwards. It is a puncture wound simply as that.
Mine healed rather quickly and has been pierced since Sept. of 06'. My husband likes it, I like it and I always have some sort of jewlery in it. I never have a problem with my pants bothering it or anything like that.
I would never pierce any other body part though.
