I was 19 when I got my tattoo. I thought about it for five years. I then consulted the artitist, had it drawn, and played around with the colors.
Mine is around my ankle, like a bracelet. I have three dolphins separated by three stargazer lilies. My tattoo represents my favorite animal and my favorite flower. Three is also my favorite number.
In addition, my parents couldn't wait to see it. My mother even paid for it. My father has two, my sister has one, and my brother has three.
As long as you give it some thought and it has meaning, a tattoo is a wonderful thing.
I also have piercings: three in my left ear, two in my right ear, my belly button, and my tongue. I love them, too. I don't see anything wrong about it. I had my tongue pierced when I was 18 (22 now), and I've never regretted it. Same with my tattoo.
