I have 3 in each lobe, and a helix on my ears (but I only ever wear one set in my lobes now, really.) Everything else I just leave.

I have my nose pierced. I've had both sides done but the left side I let close up because I got the dreaded bump and got the right side pierced. I wear it occasionally but not all the time. I would always suggest getting nose piercings done with a needle (or all piercings, actually. They're safer. Sterile.) Pros of Needle Piercings and dangers of Gun Piercings.

I had my navel/belly button pierced but it closed up. I want to get that re-done.

My addictions? Cigarettes. So not a good one. Red bull. Also not good!
