The therapist gives you homework—an exercise developed by Masters and Johnson, the duo made famous for their study of the sexual response. Every week, you and your husband lie in bed and touch each other sensually, which is not the same as sexually. You’ve never touched him, or anyone, like that—without an end goal in mind. So you feel like a weirdo at first, lightly rubbing your hand along his chest and down the side of his waist. He touches your back and thighs. Neither of you are supposed to talk, so you play the same instrumental Nels Cline album, Lovers, every time.
