Recent research has supported the positive effects of self-compassion for couples' relationships; however, these efforts have only recently been applied to couples' sexuality. Although there is some evidence supporting the associations between self-compassion and sexual satisfaction when satisfaction is conceptualized unidimensionally, it is unclear if and to what degree those associations are different for satisfaction and dissatisfaction when these constructs are assessed separately. The aim of this study was to understand the associations between self-compassion separately for sexual satisfaction and sexual dissatisfaction for romantic partner dyads. A sample of 230 married midlife Canadian couples participated in an online survey. Findings from distinguishable Actor Partner Interdependence Models indicated that women and men with higher levels of self-compassion reported more sexual satisfaction and less sexual dissatisfaction but the effects were stronger for satisfaction than dissatisfaction. Only men's self-compassion affected women's sexual dissatisfaction, but not vice versa. Findings are discussed in terms of their relevance to societal attitudes and application to sex and couples' therapy.
