Sexual Motivation and Satisfaction Among Consensually Non-Monogamous and Monogamous Individuals

Background: Previous research has found differences in sexual motives and, separately, sexual satisfaction in consensually non-monogamous (CNM) and monogamous individuals and that these constructs are related to relationship outcomes (eg, relationship quality). Aims: The present study sought to refine and expand on previous research by (i) using a more common, validated measure of sexual motives, (ii) measuring sexual satisfaction with multiple partners within CNM relationships, and (iii) examining how sexual motives are related to sexual satisfaction in CNM relationships. Methods: Participants were recruited from a university and using online forums that CNM individuals frequently use (eg, reddit, Facebook). Individuals recruited included those in non-exclusive relationships with one partner ("non-exclusive single-partner;" n = 40), those in non-exclusive relationships with more than one partner ("non-exclusive multipartner;" n = 87), and monogamous individuals (n = 322). Data were analyzed using multivariate analysis of variance and hierarchical multiple regressions. Outcomes: The main outcome measures of this study are scores on the Why Humans Have Sex Scale and the New Scale for Sexual Satisfaction. Results: Non-exclusive multipartner participants were more motivated to have sex for physical motivations compared with monogamous participants. Although there were no significant differences in sexual satisfaction when comparing monogamous with non-exclusive multipartner participant's secondary and primary partners, unique patterns of sexual motivations were associated with sexual satisfaction based on relationship configuration. Clinical Translation: Understanding the unique sexual motives associated with sexual satisfaction in various relationship configurations may help improve clinical approaches to couples counseling for both CNM and non-CNM populations. Strengths and Limitations: Data were collected from CNM participants in a variety of relationship configurations and provide analyses comparing primary and secondary partners. However, these results are limited by a small sample of CNM participants who were intentionally recruited from self-identified CNM e-forums. Conclusions: These findings add further understanding to the unique traits that characterize CNM individuals and the underlying motivational framework that may encourage individuals to initiate and maintain CNM relationships.
