ABSTRACT
This chapter is based on a study that examined the prevalence of (non)monogamy agreements and their association with positive relationship quality outcomes (commitment, satisfaction, closeness, and sexual satisfaction) (1) in cisgender female-female relationships, cisgender male-male relationships, and relationships where one or both partners do not identify as cisgender, and (2) in legally married versus unmarried lesbian, gay, bisexual, transgender, and queer (LGBTQ)+ relationships. Data were collected across two years from an anonymous US national sample (N = 1,950) of lesbian, gay, bisexual, and transgender (LGBT) participants. Our results show that the majority of LGBT couples had agreed to be monogamous (60%–77%). In addition, relational quality was generally higher among monogamous couples and married couples when compared to nonmonogamous and unmarried couples. Results also show that marriage and (non)monogamy agreement status did not interact to influence relational quality.
