Why People Have Sex Out of Obligation: Insights from Psychologists
In romantic relationships, individuals sometimes agree to intimacy not out of desire but to avoid hurting their partner's feelings or losing their interest. Psychologists have examined the personality traits and relationship dynamics associated with this behavior and whether these patterns manifest similarly in men and women.
Sex is often seen as a way to express attraction and love, but not all sexual encounters are motivated by pleasure and desire. The concept of duty sex refers to engaging in intimacy to maintain a relationship, soothe a partner, or avoid conflict.
This is not merely sexual consent without desire; it involves motivation tied to obligations toward a partner. Previous studies have linked this behavior to sexual dissatisfaction, but the factors driving it have not been thoroughly explored.
Researchers from the University of Texas at Austin investigated whether the frequency of duty sex is related to concerns about a partner's infidelity, self-perception of attractiveness, and anxiety. The study involved 252 participants aged 18 to 24 from the United States: 176 women and 76 men. All were in relationships and sexually active in the four weeks prior to the survey.
The most consistent finding was the link between duty sex and fears of a partner's potential infidelity. The higher participants rated the likelihood of their partner cheating, the more frequently they reported engaging in sex out of fear of losing their partner's love, provoking anger, or causing a breakup. This connection was evident in both the overall sample and in separate analyses of men and women.

The authors of the study proposed an explanation. A person fearing infidelity may perceive refusal of sexual contact as an additional threat to the relationship: they may feel that their partner will become upset, withdraw, and seek intimacy elsewhere. In such cases, sex becomes a means to retain the partner and reduce the risk of separation.
Additionally, participants assessed how attractive they considered themselves and their partners. In the overall sample, individuals who rated themselves lower than their partner were more likely to report duty sex. This sense of inequality may make relationships feel more vulnerable: they may fear that their partner will find someone more attractive. When analyzing men and women separately, this pattern was statistically significant only among women.
Duty sex was also linked to neuroticism—a trait characterized by heightened emotional sensitivity, anxiety, and strong reactions. Participants with higher neuroticism scores were more likely to report such behavior. This connection persisted even after accounting for concerns about infidelity and differences in attractiveness ratings. Researchers suggested that individuals who fear rejection and losing their relationships may engage more frequently in behaviors they believe help maintain attachment.
The context of the relationship also mattered. In the overall sample, individuals in serious relationships were more likely to engage in duty sex than those dating without commitments. With greater emotional involvement, the potential loss of a partner may seem more significant, intensifying the desire to maintain the connection, psychologists explained. However, the duration of the relationship did not play a significant role.
Overall, the average levels of duty sex were low for both genders. Women scored 5.24, while men scored 4.76.
In conclusion, the study's findings align with the notion that duty sex is a strategy to preserve relationships. However, it remains unclear whether this behavior strengthens intimacy in the long run or, conversely, exacerbates sexual dissatisfaction and tension within the couple.
