A recent meta-analysis found no significant difference in overall relationship or sexual satisfaction between monogamous and consensually non-monogamous partners. This challenges the cultural hierarchy that often favors monogamy without questioning. The study, which included data from North America and parts of Europe and Australia, concluded that the quality of connection and communication within a relationship is what predicts satisfaction, regardless of the structure.

The findings suggest that exclusivity does not automatically equal quality in a relationship, and that non-monogamous arrangements can lead to negotiated behavior with rules, transparency, and consent. While the research has limitations, including samples and self-reporting biases, it sheds light on the importance of consent, clarity, and communication in relationships, regardless of whether they are monogamous or non-monogamous. This information provides individuals with the freedom to choose a relationship structure that aligns with their values and needs, rather than conforming to societal expectations.
