Women's sexual satisfaction as a predictor of well-being in same-sex versus mixed-sex relationships.

Structural equation modelling was used to assess the strengths of the links between sexual satisfaction and self-reported (a) relationship well-being, (b) mental health, and (c) physical health for women in same-sex (i.e., homosexual, n = 114) versus mixed-sex (i.e., heterosexual, n = 208) relationships. Participants came from a large-scale Internet study. Sexual satisfaction was found to be an extremely strong predictor of relational well-being, a strong predictor of mental health, and a weak to moderately strong predictor of physical health. A two-group comparison model indicated that the strength of these links was the same, regardless of whether the women were in a sexual relationship with a man or with another woman.
