Well Im 16..And I got my belly button pierced when I was 15, as a christmas present from my boyfriend. I went to Moniques Euro tattoo parlour in Auckland, New Zealand. They were very clean and professional. I was freaking out over it as this was my first major piercing. My b/fs sister was getting her first tattoo at the same time, so everyone was prettty anxious. He marked me up, swabbed my belly button. Told me to lay down and then in like a second the needle was in and out. And I had a new piercing!. The fact that it was done so fast gave me a fright so I ended up nearly ripping my b/fs hand off. lol.
But after he told me how to care for it, It didnt even hurt. My advice is if your considering getting this piercing. Get it, Its totally painless and looks hott.
