Erotic tattoos. Why are they so interesting?

It does not seem to matter whether you are a hot girl with tattoos or a guy with a tattoo of a hot girl, erotic tattoos are super sexy.

Of course some of the first imagery that comes to mind when you say erotic tattoo is that of the pin up girls that sailors often got when on shore leave. Bikers are well known also for having some half naked tramp on an arm or leg, often resembling a female companion from one time or another in their life.
Now days the women in tattoo art are more complex and stylized than in days gone by though Betty Page and pin up girls are still among the top chosen.
