Evolved to be connected: the dynamics of attachment and sex over the course of romantic relationships

Gurit E Birnbaum et al. Curr Opin Psychol. 2019 Feb.

Abstract

Sexual urges and emotional attachments are not always connected. Still, joint operation of the sexual and the attachment systems is typical of romantic relationships. Hence, within this context, the two systems mutually influence each other and operate together to affect relationship well-being. In this article, we review evidence indicating that sex promotes enduring bonds between partners and provide an overview of the contribution of attachment processes to understanding the sex-relationship linkage. We then present a model delineating the functional significance of sex in relationship development. We conclude by suggesting future directions for studying the dual potential of sex for either deepening attachment to a current valued partner or promoting a new relationship when the existing relationship has become less rewarding.
