Predictors of duty sex frequency in women.

Background: Duty Sex-the act of engaging in sex out of a sense of duty or obligation to a partner-is a commonly reported reason why women have sex, with studies indicating associations between Duty Sex and sexual dysfunction, as well as nonconsensual sexual experiences (NSEs).

Aim: This study sought to examine the associations between Duty Sex frequency, sexual function, and NSEs using comprehensive, validated measures of sexual function and NSE histories in a large community sample of women.

Methods: Six hundred and fifty-eight women with (n = 293) and without (n = 365) NSE histories completed measures of sexual function and sexual motivations.

Results: Women with NSE histories reported more sexual pain, lower sexual satisfaction, and more frequent Duty Sex. The relation between NSE history and Duty Sex remained after controlling for the variance in sexual function. The type of NSE behavior, but not the timing of the first NSE nor the perceived impact of the experience, predicted Duty Sex frequency.

Clinical implications: Clinicians should consider sexual motivations, particularly Duty Sex, when treating women with NSE histories or who experience sexual dysfunction.

Strengths and limitations: To our knowledge, this was the first study to examine how NSEs relate to all domains of sexual function and sexual motives, revealing a link between NSEs, sexual function, and Duty Sex. However, we were unable to account for what percentage of sexual encounters are considered Duty Sex. Therefore, our measurement of Duty Sex lacks specificity, which may explain the relatively low variance accounted for by the models in our analyses.

Conclusions: There are consequences of NSEs, including difficulties with communicating sexual boundaries and impairment of sexual function, that may contribute to the increased likelihood of engaging in Duty Sex.
