It's difficult (read: impossible) to accurately assume anything about a person based on how they look. Sure, you can make sweeping generalizations and maybe you'll be right every once in a while, but people are complicated and something as shallow as appearance cannot possibly capture the entirety of a human being.
Unless, of course, that human being has tattoos.
The presence of a little ink can tell you a lot about an individual: what they've learned about and applied to parenthood, how creative they are, how good (or bad) of a parent they are (according to some people) and, yes, how great they are in bed. It's safe to assume, in fact, that anyone with a tattoo is dynamite in bed, and their tattoos are proof that when it comes to throwing down they're the best of the best. If they have a cute rib tattoo, you know they're not afraid of a little pain. If they have a simple, small tattoo, you know that even if they're sometimes shy, they'll always find a creative way to express themselves. And if they're completely inked out, well, you know that there is next to nothing that a tattooed woman wouldn't try or attempt at least once.
Should we go around judging people (and their abilities) based on how they look? Well, of course not. But if you see an inked woman, you might as well save yourself some time and just assume she's amazing in bed. Here are nine reasons why, in case you have trouble and really want to cut your getting-to-know-you time in half.
