Does Sex Matter? The Role of Sexual and Relationship Satisfaction on Living Apart Together Relationship Transitions

There is limited understanding of how the aspects of sex and relationship quality are related to decisions on whether to move in together, separate or continue dating among living-apart together (LAT) couples. This paper focuses on sexual and relationship satisfaction in understanding LAT relationship transitions into coresidence or separation in Germany. The longitudinal prospective design of the German Panel Analysis of Intimate Relationships and Family Dynamics data (pairfam, waves 1-9) is used. Discrete-time competing risk hazard models on LAT relationship outcomes to coresidence or separation are estimated. The results underline the fact that sexual satisfaction is not related to LAT partners' decision to move in together; however, higher levels of relationship satisfaction are positively related to the decision of moving in with a partner. The models reveal that low sexual and relationship satisfaction are associated with breaking-up relative to still living apart. This study highlights the importance of considering sexual satisfaction in understanding better the risk of separation from a LAT partner, in addition to the global indicator of relationship satisfaction.
