I used to have both ears and my tounge pierced. Took them out once I started working professionally. So now I'm just sticking to tattoos
I dunno. Not a big fan myself of nose/lip/eyebrows. So that really leaves the ears and the nips. And I guess the scroat too.
I'd suggest though that for any piercing, stick to a place that only does that, as opposed to a place that does tattoos/piercings. In most of those places, the piercing is a side job to help make money when tattoos are slow. A piercing only parlor will be much more knowledgable, safe, and skilled.
