A study published in the Journal of Sex and Marital Therapy indicates that a notable number of women with no sexual desire engage in sexual activity primarily to maintain their relationships. Researchers analyzed data from drug trials for hypoactive sexual desire disorder, characterized by a chronic lack of sexual cravings. Participants in these trials, which included treatments like a testosterone patch, bremelanotide, and flibanserin, reported having sex approximately two to three times per month before treatment, despite lacking desire.
The study's findings suggest that this practice, termed "mercy sex" by the researchers, is motivated by factors beyond sexual arousal or pleasure. One significant driver appears to be the desire to foster monogamy and prevent partners from seeking intimacy elsewhere, adhering to the notion that shared sexual experiences can strengthen a couple's bond.
Evolutionary and Social Factors
Researchers Nikita Guptan and James A. Simon of IntimMedicine Specialists in Washington, D.C., posited that evolutionary differences in reproductive strategies may play a role. They suggested that while men historically may have sought to reproduce with multiple partners, women's strategies often prioritized stability and resource sharing for child-rearing. Engaging in "mercy sex" could have been a way to ensure a partner's continued presence and support for raising offspring.
Furthermore, the study notes that men are often socialized to equate sex with emotional closeness. Therefore, consensual, though not desired, sexual activity by women might serve to preserve this perceived emotional connection. However, these evolutionary explanations were found not to apply to women in same-sex relationships or those without partners.
Broader Implications and Nuances
The phenomenon of "mercy sex" is not isolated to the study's participants. A 2024 study in the Journal of Sex Research found that a majority of individuals have consented to sex they did not desire at some point, including within their current relationships. Psychologists, as reported by Forbes, highlight that when lower-desire partners engage in sex solely to avoid conflict or disappointment, it can lead to the suppression of their own needs and potentially contribute to depressive symptoms.
It is important to distinguish "mercy sex" from instances where initial neutral desire leads to arousal during intercourse, a pattern common in many healthy long-term sexual relationships. The researchers concluded that clinical trials for sexual desire disorders should consider evaluating the quality of sexual experiences, not just the frequency, when measuring treatment success. The first drug approved by the FDA for hypoactive sexual desire disorder in premenopausal women was flibanserin in 2015.
