Yes! Piercings are very very addicting. I had four at one point and wanted three more and my boyfriend said I was going to look like a jewelry store. Gauging is the same way! I wanted 00 but ended up at half inch wanting to go bigger. I have one tattoo, only because I can't afford more!
Sadly, the one piercing I really want, I doubt I will ever be able to get. Tongue. I can't have visible piercings at work obviously .. and the tongue needs a good bit of healing before one starts using clear spacers or the like. Ah well. Obla dee, obla day. Life goes on.
