9 Sex 'Rules' to Break Tonight

First, nine commonly swallowed sexual misconceptions, and the truth, which shall set your sex life free. Oh, and since we all know there can be too much of a good thing (think: Matthew McConaughey, shirtless), we recommend you not trot them all out tonight, lest your regular bedfellow suddenly wonder whom he brought home. Of course - and this should go without saying - safety first, ladies. The worst sex is the type that ends with you going, "Oh no, what if...?"

7. Men Really Don't Like "Going There"
Did we mention that Ian Kerner also wrote a book called "She Comes First"? That's right, an entire book devoted to teaching men how to pleasure you. Here's what he found out, in the process, about how guys feel about going down: "In my experience, 90 percent of discomfort around oral sex comes from women who are afraid they don't taste or smell good, or are afraid they're taking too long.
