Book excerpt: Kim Lee is a psychotherapist with more than 20 years of experience helping clients work through difficulties with relationships and break-downs in communication, including issues of trust and infidelity. Along with her husband, she is also a swinger, a secret unknown to even her children or closest friends. In this memoir, Kim Lee takes readers inside the secret society of swingers, also known as "the lifestyle." Sex plays a dominant role, but the book's focus is also on human connection and relationships beyond sex. She shares the difficulty of working through her husband's affair and navigating relationship issues that both swingers and non-swingers commonly face. Lee invites the reader to learn from her mistakes and see how to better safeguard their own relationship, regardless of niche lifestyle choice. While marriage is imperfect and hard, she demonstrates that it can also be vibrant, healthy, and even sexy, if both partners put in the work and communicate honestly with each other.
