If a guy ever spreads a rumor that he slept with you, don't deny it. One, because there will always be people who will think it's true, and two, because that dumbass just handed you the power to say anything you want about what he's like in bed, and people will believe it. Say he bleats like a sheep when he orgasms. Say he puts on pearl earrings and asks you to call him Daisy. Say he couldn't get it up until he watched an old Billy Mays infomercial. The power is yours.
