It's not easy to understand precisely what makes a tattoo sexy, but part of it is the changing nature of the tattoo culture. At one time, tattooing was limited almost exclusively to men. The assertive women who break this gender barrier demonstrate that they are rebellious, which many men like to see in a woman.
Lots of men find this rebellion attractive. They want a woman who isn't afraid to be a little wild and crazy, and who is willing to let her hair down. There's no better way to show that you're decisive and ready to have fun than by getting a sexy tattoo. This is an easy way to signal to men that you're brave and daring without every saying a single word.
