Meta-Analysis Finds Equal Relationship and Sexual Satisfaction in Monogamous and Consensually Non-Monogamous Relationships

# What the ‘monogamy-superiority myth’ Gets Wrong About Relationship Satisfaction

### 1. What is happening? (The Essence)
A new peer-reviewed meta-analysis in *The Journal of Sex Research* reviewed 35 studies involving 24,489 participants and found no significant differences in relationship satisfaction or sexual satisfaction between monogamous and consensually non-monogamous people. The findings challenge the ‘monogamy-superiority myth’—the assumption that monogamy is inherently healthier, happier, or more stable than other agreed-upon relationship structures. The review included different forms of consensual non-monogamy, including open relationships and polyamory, and found broadly consistent satisfaction patterns across demographic groups.

### 2. The Somatic & Systemic Context
The wider context, reflected in reporting from PsyPost and the full journal publication, is not that one relationship model is “better,” but that relational quality depends on the conditions inside the relationship: consent, clarity, communication, emotional regulation, and mutual care. From a somatic perspective, the body often responds less to the label of a relationship and more to the felt experience of safety, coherence, honesty, and repair after rupture.

Systemically, consensually non-monogamous people may still face stigma, social misunderstanding, and assumptions that their relationships are unstable or less committed. That external pressure can create additional nervous system load: concealment, hypervigilance, fear of judgment, or the need to over-explain one’s relational choices. For practitioners in intimacy and relational work, the study supports a more inclusive frame: relational health should be assessed by consent, attunement, boundaries, and lived satisfaction—not by whether the structure matches dominant cultural norms.

### 3. The Dual Perspective

#### What this means for daily life
If you are in a monogamous, open, polyamorous, or otherwise consensually non-monogamous relationship, this research suggests that your relationship structure alone does not determine whether you can feel satisfied, connected, or sexually fulfilled. What matters more in daily life is whether your body has enough evidence of trust: clear agreements, honest conversations, respected limits, and space to name discomfort without being dismissed.

For the nervous system, ambiguity can be costly. If agreements are unclear, the body may register tension as restlessness, shutdown, jealousy, looping thoughts, or exhaustion. This does not automatically mean the relationship model is wrong; it may mean the relational container needs more clarity, pacing, or repair. A useful self-check is: “Do I feel free to speak honestly here, and do my boundaries change how we act—not just how we talk?”

#### What this means for your practice
For coaches, somatic practitioners, and intimacy professionals, the study reinforces an ethical baseline: do not treat monogamy as the default marker of relational health. Assessment should focus on consent, mutuality, emotional capacity, communication patterns, power dynamics, and whether clients can make agreements that are realistic for their nervous systems and daily lives.

In practice, this means avoiding pathologizing consensual non-monogamy while also avoiding romanticizing it. Open or polyamorous structures require concrete skills: negotiation, repair, pacing, body-based boundary awareness, and the ability to distinguish activated attachment responses from actual agreement violations. Practitioners should remain within scope: support regulation, communication, and embodied consent; refer to licensed mental health or medical professionals when clients present with severe distress, coercive dynamics, psychiatric concerns, or risk-related issues beyond coaching or somatic education.

### 4. Key Takeaways
* Relationship satisfaction is not determined by structure alone.
* Consent, clarity, and regulation matter more than cultural conformity.
* Practitioners need inclusive, non-pathologizing frameworks for relational work.
