In the quiet moments of a committed relationship, when the house is still and thoughts wander freely, many men find themselves contemplating a particular kind of loss—not of what was, but of what could have been. Sexual FOMO (Fear of Missing Out) in monogamous relationships is rarely discussed openly, yet it affects countless committed partners who wonder about unexplored sexual experiences and paths not taken.
This feeling isn’t about dissatisfaction with a current partner, but rather a complex emotional response to the natural limitations that commitment brings. At Klarity Health, our therapists regularly work with individuals navigating these complicated feelings—the intersection of love, commitment, sexual identity, and the very human tendency to wonder ‘what if?’
Sexual FOMO often emerges from several psychological factors:
Dr. Justin Lehmiller, a research fellow at the Kinsey Institute, notes that ‘Sexual curiosity and fantasy about others is completely normal, even in happy relationships. It doesn’t mean there’s something wrong with your relationship or that you don’t love your partner.’
For many men who committed early in their lives, the mathematical reality can feel stark: one sexual partner for potentially 50+ years. This realization often triggers complex emotions:
The foundation of addressing sexual FOMO begins with honest communication—both with yourself and potentially with your partner.
Before discussing these feelings with a partner, consider:
If you choose to discuss these feelings with your partner, approach the conversation with care:
One client at Klarity Health shared: ‘The conversation was nothing like I feared. My partner had similar thoughts sometimes. Just talking about it reduced the power these feelings had over me.’
Many therapists recommend focusing on depth rather than breadth of sexual experience:
Some couples consider various forms of consensual non-monogamy:
| Approach | Description | Potential Benefits | Potential Challenges ||———-|————-|——————-|———————-|| Fantasy-only | Keeping curiosity in the realm of imagination | Maintains monogamous boundaries | May not fully address feelings || Monogamish | Limited agreed-upon exceptions | Provides some new experiences | Requires extensive communication and boundary-setting || Ethical non-monogamy | Various forms (swinging, open relationships) | Allows for new experiences while maintaining primary relationship | Complex emotional landscape; requires significant relationship security |
Dr. Lori Brotto, a clinical psychologist specializing in sexuality, cautions: ‘Any exploration of non-monogamy should be approached thoughtfully, with clear communication, boundaries, and ideally with therapeutic support to navigate the complex emotions that may arise.’
Relationship counselors often recommend these cognitive approaches:
If sexual FOMO is causing significant distress, professional help can provide valuable support.

Therapeutic approaches might include:
Sexual FOMO in monogamous relationships is a normal experience that many people—particularly men—struggle with silently. By acknowledging these feelings, communicating thoughtfully, and exploring appropriate options within your relationship’s boundaries, it’s possible to find peace and renewed connection.
Remember that commitment doesn’t require the absence of curiosity or desire—rather, it’s about how you channel those feelings in ways that honor both yourself and your relationship. The goal isn’t to eliminate all sense of wonder about paths not taken, but to build a relationship so fulfilling that those occasional thoughts lose their power to cause distress.
Yes. Sexual curiosity and thoughts about missed experiences are common, even in loving, committed relationships. These feelings don’t necessarily indicate relationship dissatisfaction.
Not necessarily. While ethical non-monogamy works for some couples, it requires exceptional communication skills and emotional security. For many, the reality can be more complex than anticipated and may create new challenges.
Sometimes sexual FOMO masks other issues like general life dissatisfaction, fear of aging, or relationship problems. Professional therapists, like those at Klarity Health, can help you explore what’s truly driving these feelings.
With sensitivity and care, discussing these feelings can strengthen intimacy through honesty. The key is approaching the conversation with empathy and without making your partner responsible for solving these feelings.
Therapy provides a safe space to explore feelings without judgment, develop communication strategies, address underlying insecurities, and find personalized solutions that align with your values and relationship commitments.
