"Welcome to Sex Education. Now, if you're expecting a class where you learn to put a condom on a banana and look at pictures of various sexually transmitted diseases in an attempt to scare you out of ever touching yourself for the rest of your life, you're in the wrong room. If you're expecting a class extolling the virtue of waiting until you've committed your life or until you can file for divorce to someone before finding out that you're incompatible, you're in the wrong class. If you're expecting a class that will tell you nothing at all about the topic you're studying and will expect you to have utterly no practical experience with it the rest of your life, you're in the wrong class. If you have issue with everyone else in this class seeing your naked body contorted in pleasure, you're in the wrong class. If you're in the wrong class, leave now."
