How Inclusion of Other in the Self Relates to Couple’s Sexuality and Functioning – Results from the German Health and Sexuality Survey (GeSiD)

Closeness, in the sense of inclusion of other in the self, has been found to be an important factor for relationship well-being, satisfaction and pair-bonding. In the past ten years, the self-expansion theory has also been incorporated into sex research, although studies are still very scarce and not without limitations. The present research aimed at further elucidating the relevance of relational factors for couple’s sexuality, and to clarify the role inclusion of other in the self plays for sexual satisfaction and sexual distress. A broadly representative sample of 3,046 men and women aged 18 to 75 was taken from the German Health and Sexuality Survey (GeSiD). Throughout analyses, inclusion of other in the self and love were positively related to sexual satisfaction. Furthermore, inclusion of other in the self was negatively related to how strongly someone was distressed by experiencing sexual problems. Closeness seems to have a compensatory role especially for women with sexual problems, protecting them from experiencing sexual distress. In future research, couple’s sexual satisfaction should not be compartmentalized from relational aspects. Results clearly promote the Inclusion of Other in the Self Scale as an interesting tool for both research and treatment.
