I think it's really cool that you want a tattoo.
However, there's no need to rush into it, right? I'd suggest waiting until you're 18 and can legally get it done in your state. Last year when I was 16 I really, really wanted a tattoo, but then I decided that I didn't. So it's quite possible that you could change your mind between now and your 18th birthday. You want to make sure this is something you will be happy with for the rest of your life, because, of course, it's permanent. I'm not trying to discourage you at all if this is what you really want, but just keep that in mind and be careful.
