I love it when girls have tattoos, provided they're tasteful and creative. I see girls with badly done lower back tattoos or something cliche like birds all the time and just kind of face palm at them.
You should wait a few years to get one. People change a lot as they make the transition from teenager to adult.
theres very few things that I can say I would NEVER do. getting a tattoo is one of them. however I don't mind if girls have tattoos (or guys for that matter). you could have longsleeve tattoos for all I care lol, if you like your tattoos then its cool :)
I have a quote on the back of my neck, the only way you see it is if my hair is up. People really like it, both men and woman. It's not just a bird or something that doesn't mean anything, and its not out in the open. Sometimes people forget I have it because I rarely wear my hair up. If I were you, think of jobs, some jobs won't allow you to have them, so get it somewhere you can hide it if necessary.
