Countering the ‘monogamy-superiority’ myth: Relationship satisfaction, stigma and health education implications

Background: This discussion paper addresses the health education implications of the enduring ‘monogamy-superiority’ myth – in the form of the assumption that monogamous relationships are inherently healthier, more stable or more fulfilling than consensually non-monogamous (CNM) arrangements. Summary of Evidence: Drawing on recent evidence, we highlight how relationships and sexual satisfaction do not differ significantly between relationship structures. Despite this, individuals in CNM relationships often encounter stigma, discrimination and structural barriers, which can negatively influence their well-being and deter open communication in healthcare and educational settings. Implications: For health educators and practitioners, these findings highlight the importance of inclusive, evidence-informed approaches that acknowledge relationship diversity as a legitimate and healthy variation of human intimacy. We outline key implications for practice, including challenging the personal and institutional biases that privilege monogamy; fostering safe environments that encourage open disclosure; integrating accurate information about consensual non-monogamy into health education and professional training; and advocating for structural changes that better accommodate diverse relationship configurations. Conclusion: Shifting the focus from relationship structure to the quality of communication, consent and mutual respect within relationships will allow health education to play a role in dismantling stigma and supporting more equitable and person-centred care. Embedding these perspectives into curricula, community programmes and clinical practice not only improves the experiences of people in CNM relationships but also strengthens health systems’ capacity to deliver responsive, culturally competent care.
