My mom got my ears pierced when I was a baby. But I got my cartilidge around 13 and 2 more (1 on each ear) around 14. The thing I did that was bad was I let my friend pierce my tongue when I was 15
luckily it never got infected. Then I went on to get my belly button and nose pierced. The funny thing is I only kept the regular holes for the ears and the belly ring. I let the rest close.
