Each new body part revealed seems like a revelation, a prize somehow. Other reasons to keep your clothes—at least some of them—on during sex: Remember how hot it was when you first met someone and you were making out forever, fully clothed and just sort of desperately pressing and rubbing against each other? And having just enough clothes off to get body parts to where they want to be makes sex feel spontaneous, like, We must do this NOW. Give some epic oral while keeping their underwear on or sorta on the entire time. Start by kissing up their thighs, across their belly, around their underwear. When you finally, finally slide their underwear to the side to get your wet mouth on them, there will be nothing they want more.
