Sex-specific need fulfillment in relationships and sexual and relationship well-being

Sexual activity can provide important opportunities for fulfilling experiences that contribute to greater relationship satisfaction and overall well-being, yet young adults are reporting fewer partnered sexual interactions. According to self-determination theory, when people perceive their needs for autonomy, competence, and relatedness are met in relationships, they report greater relationship and sexual well-being, whereas need frustration contributes to relationship dysfunction and dissatisfaction. In the current cross-sectional study, we extend these ideas to a sexual context. We hypothesized that sex-specific need satisfaction would be associated with higher sexual desire, sexual satisfaction and relationship satisfaction and lower sexual distress beyond that of general need satisfaction within one’s relationship. We expected opposite associations for sex-specific need frustration. Partnered individuals aged 18–29 ( N = 197) completed online measures of sexual and relationship need satisfaction and frustration, sexual desire, sexual and relationship satisfaction, and sexual distress. Controlling for need satisfaction within the relationship, which was associated with higher desire and satisfaction, multivariate regression analyses indicated that sex-specific need satisfaction was associated with higher sexual desire, higher sexual and relationship satisfaction, and lower sexual distress. Furthermore, sex-specific need frustration was associated with higher sexual distress. While need satisfaction in one’s relationship and sex life may have benefits for sexual desire and sexual and relationship satisfaction, promoting need satisfaction and minimizing need frustration specific to sex may be helpful in minimizing sexual distress. Implications for researchers and clinicians highlight the importance of distinguishing between psychological need satisfaction (and frustration) across different relational contexts.
