Relationship Satisfaction, Sexual Desire, Jealousy, and Conflict Resolution in Monogamous and Consensually Non-Monogamous Romantic Relationships

Among the models of romantic relationships, consensual non-monogamy (CNM) is one in which several affective and/or sexual relationships are allowed simultaneously. This type of relationship, still considered non-normative, has experienced a considerable increase in recent years. However, research is still limited, and studies on the subject in Spain are scarce. To better understand the differences and similarities between monogamous and CNM relationships, this study investigated both relational models, divided by sex, for four factors concerning romantic relationships: relationship satisfaction, sexual desire, jealousy, and conflict resolution styles. In a sample of 210 persons, the results showed that CNM females reported significantly higher levels of consensus and dyadic sexual desire than monogamous females. Jealousy levels were similar in both types of relationships. People in CNM relationships displayed greater conflict resolution skills through negotiation and compromise, whereas monogamous females reported using the non-constructive style of conflict engagement more than CNM females and monogamous males. CNM males indicated a greater use of withdrawal compared to CNM females. Overall, females showed more passionate jealousy than males. This investigation highlights the importance of studying romantic relationships and their different models.
