A groundbreaking meta-analysis published in The Journal of Sex Research reveals that individuals in consensually non-monogamous relationships report levels of satisfaction in their relationships and sex lives comparable to those in monogamous partnerships. The study, led by Associate Professor Joel Anderson of La Trobe University, challenges the widespread belief that monogamy inherently offers greater fulfillment.
The research analyzed data from 35 studies involving 24,489 participants across the United States, Canada, Australia, and several European countries. It found no significant differences in satisfaction between monogamous and non-monogamous individuals, whether in terms of trust, commitment, intimacy, or sexual fulfillment. Non-monogamous arrangements included open relationships and polyamory, with similar results across LGBTQ+ and heterosexual demographics.
Associate Professor Anderson highlighted the “monogamy-superiority myth,” a societal assumption reinforced by stereotypes and media narratives. He suggested that infidelity, a common issue in monogamous relationships, is often irrelevant in non-monogamous partnerships due to pre-established agreements between partners.
Despite these findings, non-monogamous individuals frequently face stigma, discrimination, and barriers in healthcare and legal systems. The study calls for greater inclusivity in recognizing diverse relationship structures to better support well-being and reduce societal biases.
“Our findings demonstrate that people in consensually non-monogamous relationships experience similar levels of satisfaction as those in monogamous ones, despite societal scrutiny,” said Professor Anderson. “This challenges the outdated notion that monogamy is the only path to fulfilling relationships”
The study underscores the need for broader acceptance of diverse relationship structures, urging healthcare professionals, therapists, and policymakers to move beyond monogamy as the default ideal. While the research focused on Western populations, it opens the door for further exploration of cultural perspectives on non-monogamy.
