Reddit mentions of Let's Talk About... Non-Monogamy: Questions and Conversation Starters for Couples Exploring Open Relationships, Swinging, or Polyamory (Beyond the Sheets Book 2)

It's actually a series of conversation starters and discussion questions for couples to help them explore what types of non-monogamy might work best for them, define their boundaries, and clarify their sexual needs and desires. It's great for people interested in the lifestyle, or couples already in the lifestyle who need to improve their communication.
