Quote from : Suck It, Wonder Woman!: The Misadventures of a Hollywood Geek Book

Listen to Your Lover (Or Babe, Sweetie Cakes, Hot Rod, Honey, Dancing Queen, Dairy Queen, etc.) If she tells you she likes it when you bite her neck—do it! It doesn’t matter where she learned that she likes it or why she does, just be thankful you got the tip. Girls don’t always express what they want, so when she does say it, you really want to make sure you are paying attention. Also, learn her language (unless it is Mandarin, because that shit is impossible). If you start pulling her hair and she starts moaning, that’s her way of saying, “Ohmygod, please do this more, and by more I mean all the time.” And the more you please her, the more she’ll want to do it with you. It’s a win-win!
