If you already watch porn, you'll be happy to know that seeing skin flicks with your partner (as opposed to alone) is good for your bond. According to a study published in The Archives of Sexual Behavior, unmarried couples who watch porn together rate their relationship as more committed and sexually satisfying than those where one partner sneaks it when the other isn't home. "Couples who watch sexy movies together — and 45 percent do — are making porn a shared sexual experience, which is healthier for your bond than a secretive one," says Galena K. Rhoades, Ph.D., of the Department of Psychology at the University of Denver. "Also, you're choosing films that interest you both, so you learn something new about each other's sexual tastes, which adds novelty to your sex life."
