So I'm looking into getting my tongue done and I have done some research and am fairly sure it's what I want and I can put in the care to make sure it heals properly.
But there's this one thing that has been really niggling at me, and I don't want to go for it unless I know the answer:
Basically, when the piercer puts the dot on your tongue to mark where the needle is going, is that pen a one-time use thing that he'll throw out afterwards, or is the pen used on everyone for anything? Seriously, it's really bugging me and I don't want to get the piercing if the pen is used on multiple people for various piercings ><
