I haven't read all of the posts, you may have said how old you are and what your ambitions are and where you are in your pursuit of a career? My opinion isn't any different than others that have recommended against it, my personal taste, don't like them at all.
I did many things when I was growing up without too much forethought, now I can look back and can see that I wasn't very wise with some of my decisions. I've also found that opportunity present themselves and when you least expect it, that could apply in your social and professional life. How you act or look today could impact someone decisions tomorrow.
I'm sure that you're a beautiful young lady just as you are, why do you need an extra hole in your head?
