I have the navel done. Did that 8 years ago when I was in high sdon'tchool. It was also when EVERYONE was having it done. I did it because I wanted it. I like it and have always had a thing in it but sometimes I forget it's there. My sister and mom got it done too and my dad drove to the tattoo parlour so I can't claim it was to upset my parents. Lol I wouldn't get any others, not even second holes in my ears. I don't understand putting metal in one's face or gauging one's years. That just looks unprofessional and lower class to me.
Guess I'm pretty tame, or maybe lame I only have two holes pierced in each ear. Not planning any others. I got the second holes when I was given a pair of diamond studs that I wore constantly for a while, now I only wear the diamonds every once in a great while.
I got mine because I truly wanted them for myself, I have 5 on each ear and a nose ring, I'm planning on getting a navel piercing too, I can't explain why I wanted them I just find them interesting to have I guess.
