Attachment Orientations, Sexual Behavior, and Relationship Satisfaction in Young, Mixed-Sex Couples: A Dyadic Approach.

We examined if and to what degree attachment orientations of both partners moderate the link between different behavioral characteristics of the sexual relationship and relationship satisfaction in the early stages of romantic attachment. A sample of 126 young, mixed-sex couples ( = 252, mean age = 23.3,  = 2.4; average relationship duration = 1.9 years,  = 0.9) filled out questionnaires assessing attachment anxiety and avoidance, a range of intimate and sexual couple behaviors, and relationship satisfaction. Exploratory factor analyses revealed two behavioral factors: Intimate behavior (kissing, cuddling) and sexual behavior (oral sex, coitus). Although frequency of sexual behavior was not directly associated with relationship satisfaction, we found a significant positive interaction with anxious attachment, indicating that higher frequencies of sexual behavior were associated with greater self-reported relationship satisfaction in more anxiously attached individuals. Exploration of the effects of intimate behaviors on relationship satisfaction revealed significant positive associations as well, but, unexpectedly, only for avoidantly attached individuals. These results call for a dyadic and differentiated approach to the study of sexuality in couples and are in line with prior findings that the impact of intimate and sexual behaviors on relationship satisfaction varies depending on attachment orientations.
