In this study, the author compared the relationship quality of sexually monogamous and nonmonogamous gay male couples. Among a nationwide surveyed sample of 121 gay male couples, no differences were found between strictly monogamous and openly nonmonogamous couples on scores of the Dyadic Adjustment Scale (DAS). In addition, mean DAS scores for both groups were within functional ranges. However, self-reported monogamous couples in which 1 or both members engaged in extrarelational sex were less adjusted and satisfied than their nonmonogamous and strictly monogamous counterparts. The findings suggest that for some gay men, sexual monogamy may not be a necessary component of a satisfactory, committed relationship, and social workers assisting gay male couples might need to reconsider traditional ideas about sex, intimacy, and commitment.
