Introduction Attachment theory provides a framework for understanding sexual satisfaction; in general, research suggests that attachment anxiety and avoidance are associated with decreased sexual satisfaction. Given their different working models of self and other, perceptions of the partner's level of satisfaction might differentially influence people's own perceptions of satisfaction based on their attachment avoidance and anxiety. Aim To examine the predictive value of attachment anxiety and avoidance and perceptions of partner satisfaction in predicting physical and emotional satisfaction after sexual interactions in two studies. Methods Participants (study 1, n = 52; study 2, n = 144) completed a one-time survey containing a measurement of attachment and then reported on their physical and emotional sexual satisfaction after each sexual interaction over the course of 2 to 3 weeks. Main Outcome Measures The Experiences in Close Relationships Scale–Revised was completed during the one-time survey, and ratings of personal physical and emotional sexual satisfaction (studies 1 and 2) and perceptions of partner's physical and emotional satisfaction were completed after sexual interactions (study 2). Results Greater attachment avoidance was associated with lesser physical and emotional satisfaction. Moreover, when perceiving the partner to be emotionally satisfied, people with more attachment avoidance reported less emotional satisfaction for themselves. For greater attachment anxiety, greater perceived partner satisfaction (physical and emotional) predicted greater personal satisfaction of the two types. Conclusion The findings support attachment theory as a valuable lens through which to study sexual satisfaction. Moreover, the results suggest that it is important to consider perceptions of partner sexual satisfaction in understanding the sexual satisfaction of people who demonstrate attachment anxiety and avoidance.
