I also love corset piercings and I may get one when I turn 18 (and am safely out of the house).
I have had 6 over the years, but I only have my ears currently. Eyebrow, tongue, and as SK has said, 2 that wont be mentioned.
I regret taking out all of them but at this point could deal with not having my eyebrow pierced. Looking for a professional job at the moment.
Also, a heads up on the corset piercing! They are indeed very beautiful but they are a surface piercing which means it is temporary. Because your back is always moving it wont be able to heal properly, and so it is easier for your body to reject (push out) them than to keep them. Often this leaves nasty scarring if not dealt with right away.
