A sixty-seven-year-old woman keeps a collection of well-endowed lovers in various corners of the world; a restaurant owner is jolted back to life when she gets illicit messages from a married man; an artist attends an overwhelming sex party, only to find themselves feeling reinvigorated after they get to role play as a rock. Some diarists are just beginning to question their relationship with monogamy; others have been polyamorous for a long-time. Some accounts are graphic and dishy, while others focus on the search for lasting connections that feel genuinely liberatory. Every single one is strikingly honest and authentic, inviting us to relish the types of stories we hear in secret—the desires and fantasies that get whispered about to trusted confidantes, or relegated to the pages of a diary.
