Hi, I don't have one, and I'm in my early twenties now and I am kinda glad I don't have one cause of the pregnancy and scarring issues. There was a period of time when I was younger and wanted one, but I was too chicken to get it done. I do have many friends that have their belly buttons pierced and they like it, but said it was extremely painful and a hassle to take care of afterwards. Many if them had infections and such within the first year. I think it is cute to see a girl with a nice body sporting one. It's your body and your decision, so have fun with it!
