Well I wouldn't get a tattoo but that's not a good answer, ask yourself these questions.
1.Why am I getting a tattoo?
2.Is it an important reason?
3.When I get a boyfriend and get married would i still want it?
4.With my current job, future job or dream would embarrass me or keep me from getting to my goal?
5. In the future do you want your kids to follow your example?
6.when you get older (20,30,40,50,60,70,80,90)will you still want it?
Remember a tattoo is a permanent decision.Once you get it, it's there forever.Also a tattoo might not be a good decision if your one of those people who like staying in style and with the current fashions because as time progresses styles change and right now tattoo's might be popular but think about when your 90 in a nursing home with a tattoo
