Why Do Some Women Have Sex When They Don’t Feel Desire? Understanding the New Research on “Mercy Sex”
Sexual health is an important part of overall well-being, yet it’s one of the least discussed topics in healthcare. Many women struggle silently with concerns about low sexual desire, often believing they’re alone or that nothing can be done.
A newly published article in the Journal of Sex & Marital Therapy by Dr. James A. Simon and Nikita Guptan explores an interesting and often misunderstood topic: why some women continue to engage in sexual activity even when they have little or no sexual desire.
What Is HSDD?
The study focuses on women with Hypoactive Sexual Desire Disorder (HSDD), a recognized medical condition characterized by:
- Little or no interest in sexual activity
- Few or no sexual thoughts or fantasies
- Distress or frustration related to the lack of desire
- Symptoms that are not explained by another medical condition or medication
HSDD is one of the most common forms of female sexual dysfunction and can affect women at any stage of life.
What Is “Mercy Sex”?
The authors use the term “mercy sex” to describe consensual sexual activity that occurs when a woman participates primarily for reasons other than her own sexual desire.
These reasons may include:
- Maintaining closeness in a relationship
- Meeting a partner’s expectations
- Avoiding conflict
- Preserving emotional intimacy
- Feeling a sense of obligation
Importantly, the term refers to consensual sexual activity and does not imply coercion or abuse.
What Did the Researchers Find?
The researchers reviewed data from multiple large clinical trials involving treatments for HSDD, including testosterone therapy, flibanserin (Addyi), and bremelanotide.
What surprised them was that even though these women were diagnosed with low or absent sexual desire, they were still reporting sexual activity.
Across many studies conducted over nearly a decade, women with HSDD reported approximately 2 to 3 sexually satisfying events per month before receiving any treatment.
The consistency of this finding across different countries, age groups, and menopausal statuses led the researchers to ask an important question:
Why are women having sex if they have little or no desire for it?
The Difference Between Desire and Activity
One of the most important takeaways from the article is that sexual desire and sexual activity are not always the same thing.
Many people assume that sex only happens when both partners feel spontaneous desire. Real life is often more complex.
A woman may:
- Love her partner deeply
- Enjoy emotional closeness
- Value her relationship
- Want to maintain intimacy
while still struggling with low sexual desire.
The study suggests that measuring the number of sexual encounters alone may not accurately reflect improvements in sexual desire.
Possible Explanations
Dr. Simon discusses several theories that may help explain why women with HSDD continue to engage in sexual activity.
1. Relationship Maintenance
Many women prioritize their relationships and may choose to engage in sex to maintain connection, affection, and partnership.
2. Desire for Emotional Intimacy
Some women report that sexual activity helps them feel emotionally close to their partner, even when sexual desire itself is low.
3. Social and Cultural Influences
Cultural expectations, relationship norms, and personal beliefs about partnership may influence sexual behavior.
4. Psychological Factors
Avoiding disappointment, preventing relationship conflict, or maintaining harmony may also play a role for some individuals.
The authors emphasize that these are hypotheses, not proven explanations, and that every woman’s experience is unique.
Why This Matters
The study highlights something many women have experienced but rarely discuss openly:
You can care deeply about your partner and your relationship while still struggling with low sexual desire.
Understanding this distinction can help women recognize that low desire is a legitimate medical concern, not simply a relationship problem or a lack of effort.
It also helps clinicians better understand how to evaluate treatments for HSDD and female sexual dysfunction.
You Don’t Have to Suffer in Silence
