Somewhere you trust, which is professional, and smells clean of that sterilizing stuff.
I was lucky when i got my nipple pierced cos i had to go out of town, to a tattoo and piercing studio i didnt know, but had got told about it. It didnt smell all too clean but its all good.
Im just gonna be more careful when i go to get my clit pierced cos who knows.
If i knew the places around your area i'd advise. But i dont really...Unless you wanna travel to Brighton where i got my nipple done lol.
