Not Your Grandma's Monogamy

August 20, 2025

In this episode, we revisit a compelling conversation with Dr. Tammy Nelson, a prominent sex therapist and author of "Open Monogamy." I had the distinct pleasure of discussing the dynamic landscape of relationships, particularly the concepts of polyamory and open relationships, and how they can lead to deeper happiness and fulfillment for some individuals, especially women. Dr. Nelson provides insightful perspectives on the evolving definitions of monogamy and emphasizes that non-monogamous arrangements are not for everyone, but they warrant discussion and exploration.


Dr. Nelson shares her personal journey, revealing how her experiences as a therapist over 35 years have informed her understanding of relationships. As we discuss her latest book, I encourage her to define "open monogamy," which she describes as a commitment to a primary partnership that allows for flexible relationships with others. This concept reframes traditional ideas about monogamy, acknowledging that the landscape of love and intimacy has significantly changed, particularly over the past few decades.


We delve into the societal shifts that have led many couples to reconsider their relationship structures. Particularly striking is Dr. Nelson's observation that women have increasingly taken charge of their sexual and relational needs, often acting as gatekeepers in discussions around opening relationships. This dynamism contrasts with previous eras where non-monogamous arrangements frequently involved secrecy and deception.


Dr. Nelson describes various exercises from her book that can help couples navigate these conversations openly. She explains how foundational honesty and integrity are to any relationship, and she urges couples to examine what monogamy means to them, emphasizing that definitions may vary greatly. Each couple's journey is unique, filled with opportunities for enhancing intimacy and connection through open dialogue about desires and boundaries.


Our enlightening discussion also touches on the age-related dynamics accompanying open relationships. Dr. Nelson categorizes couples into two groups: those experiencing a resurgence of vitality in their relationships as their children grow older, and younger couples rediscovering their identities apart from familial obligations. She elaborates on how these life stages often prompt individuals to seek new experiences, which can lead to fulfilling open relationships.


Throughout the episode, Dr. Nelson highlights the importance of transparency in navigating fears about non-monogamy. She encourages listeners to engage in "what-if" conversations that allow couples to explore potential scenarios and their emotional repercussions proactively. By setting boundaries rather than rigid rules, couples can create a more fluid understanding of their relationship agreements, fostering exploration while maintaining emotional safety.


As we conclude our conversation, Dr. Nelson offers to share a complimentary ebook containing starter questions for those interested in opening discussions about their relationships. Her insights encourage listeners to embrace curiosity and vulnerability, reminding us that evolving needs in relationships require periodic reassessment and open communication.


This episode serves as a platform for exploring the intricate details of modern relationships, inviting listeners to reflect on their own paths and consider possibilities beyond traditional norms. The conversations around open monogamy open avenues for understanding and expanding love, prompting couples to engage deeply with each other as they navigate the changing tides of intimacy in their lives.
