Lol so I have a ton of piercings, I guess.
I have my ears gauged to 5/8ths. An industrial. A cartilage 6g. Orbitals in both ears. Left outer conch. Snake bites (I usually don't wear those though. They're those kinds of the piercings that I've had for so long even if I took them out for the rest of my life I'd always have holes). And my septum.
My generally rule of thumb is to never have more than two facial piercings in at any time. That said, I've also had most piercings out there; Monroe, labret, eyebrow, bridge, Medusa, etc. Piercings are something that come and go for me. If I want to have them, I get them. When I'm tired of them, I take them out. The only thing I haven't done is surface piercings or serious body modification. Those... are expensive. And I know by now that they're not for me.
I think it's important to be smart about piercings. You really do need to have the right kind of face for them. Some do, some don't. I was in a position where I could safely try different piercings with little consequence (save societal), so I did it. Over time, I've learned to manage my piercings and wear them tastefully, with the right jewelery at the right time.
