I got my bellybutton done on my 18th birthday (2001) and I had a LOT of problems with mine. First of all, the guy who did it was new at it, sort of, so he put a bigger guage than was EVER needed (10 guage
) so, mine was infected and raw for 6-8 months. I finally got it changed down to a small guage and it healed in less than a month. SO, regardless, I'm going to have a funny looking scar.
Now that it is a smaller guage, I love it. I'm not a tiny girl , by any means (I'm not a huge girl either, don't get me wrong).. but its not for anyone else.. I did it for me, and me alone.
My mom flipped out when I told her I wanted it, but I did it anyways (same with my tongue and my nose), and she didn't flip out.. not even a little.
I saw go for it, if you want it. You are an adult.
