I have a large tattoo that covers most of my right shoulder blade, planning on a couple more, I just need to decide what means something to me.

As for things like subdermals and scarification, not a fan, especially when it's shit on your face. Same kind of goes for super stretched ears, it's not something you can hide easy and when you're looking for a career, most employers are going to judge heavily how that looks, and something you did in your late teens or early 20s can screw you for life if you aren't careful. Plus, should you ever want to remove the plugs, you can't without having permenantly saggy earlimobes.
