Tongue Ring or No Tongue Ring

I don't exactly know why but i think that I really want a tongue ring. I'm almost seventeen but i do know that there are people who'd do it without needing permission from my parents.
My friend wants to get her nipples pierced. that's where i turned toward er and smacked her upside the head. I think, personally, that thats a bit disgusting.
I mean, How bad would that hurt if you got caught on something and ripped you entire nipple off.........
*squirm*
That wouldn't make me feel too sexy.
But still, i think i really want a tongue ring....
Not to mention, pie.
