There are plenty of reasons we’d encourage you to explore how an open relationship might benefit you. We hear the real stories, the honest feedback, and the personal growth journeys—because we’re right in the middle of the open relationship dating space.
But we also know that for some of you, stories aren’t enough. You want data. You want science.
We get it.
And we’ve got you covered.
Because the benefits of open relationships aren’t just rooted in authentic experience—they’re backed by research.
So, let’s dive into the science, shall we?
Open Relationships Are More Common Than You Think
There’s a lingering myth that open relationships are rare or reserved for a fringe crowd. But that’s just not the case anymore. If you’re a fan of our website, then you probably already realize this. But again, science – Let’s go!
In fact, research shows that nearly 1 in 5 Americans have been involved in some form of open relationship. That’s a sizable chunk of the population—proof that modern dating is shifting and that non-traditional structures are becoming more visible, and more accepted.
It’s not just anecdotal, either.
According to studies like those from the University of Guelph and the Kinsey Institute, interest in open relationships is on the rise, particularly among millennials and Gen Z. These groups are more likely to question traditional norms, explore ethical ways to build relationships, and prioritise communication over convention.
Whether driven by a desire for more freedom, emotional growth, or just a more honest approach to dating, people are rethinking what a relationship should look like. And in that space, open relationships are becoming a more prominent conversation point.
Relationship Satisfaction in Open Relationships
There’s a persistent (and pesky) assumption that open relationships are somehow less stable or less fulfilling than monogamous ones—but the data doesn’t back that up. Not even close.
In a study conducted by the University of Guelph, researchers compared people in monogamous and open relationships across three areas: relationship satisfaction, psychological well-being, and sexual satisfaction.
The result?
No significant differences between the two groups. In other words, people in open relationships were just as happy, emotionally grounded, and sexually fulfilled as those in traditional setups.
That’s a big deal.
It reinforces what many of us already know from experience—that success in any relationship isn’t about whether you’re exclusive or open, but whether you’re communicating, respecting boundaries, and supporting each other’s growth.
Amazing how that works out, huh?
For many people, the freedom to explore different types of connections actually enhances satisfaction. There’s room for autonomy, variety, and self-expression—without sacrificing the emotional intimacy of a committed bond.
Open relationships aren’t for everyone, and that’s okay. But for those who embrace them with care and clarity, the research shows they can be just as rewarding—and in some ways, even more so.
Trust and Communication Are the Real Foundations
We talk about this all the time! If there’s one thing open relationships must have, it’s trust and communication. While monogamous relationships often rely on assumptions—like exclusivity being the default—open relationships are built on clearly defined expectations. Building trust in an open relationship is the priority initiative. And that only works if everyone is communicating honestly.
In fact, a study from the University of Michigan found that people in open relationships reported levels of trust and satisfaction just as high—if not higher—than those in monogamous relationships.
Why?
Because open dynamics require intentional communication.
There’s no autopilot here. Open relationships work when partners actively talk about their needs, boundaries, feelings, and concerns. That might sound intense, but it often results in a relationship where both people feel more seen, heard, and respected. And that’s the key to relationship success of any sort.
Trust in this kind of structure is earned and nurtured through frequent check-ins and emotional transparency. Whether it’s discussing how a new connection is going, processing feelings of insecurity, or just setting weekend plans, open relationships thrive when communication is consistent and clear.
And yes—this level of communication often carries over into other areas of life, making the overall bond even stronger.
Open Relationships and Mental Well-Being
When thoughtfully navigated, open relationships can have a powerful effect on mental health—often in ways that traditional relationships don’t always make space for.
That’s because open relationships naturally encourage emotional autonomy and self-awareness. Rather than relying on one partner to meet every emotional and physical need, people in open relationships often explore what they want, what they value, and how they show up in different dynamics.
Research published in Psychology Today and the Archives of Sexual Behavior has highlighted some compelling insights: individuals in open relationships often report higher levels of self-esteem, reduced pressure to conform to rigid relationship roles, and even a stronger sense of identity.
Part of this is because open relationships ask you to be emotionally present—not just with others, but with yourself. You’re more likely to check in on your own feelings, work through moments of jealousy, and explore the idea of compersion—the joy of seeing your partner happy with someone else. We’ve got a whole lot to say on comparison vs. jealousy in open relationships…
This kind of emotional work builds resilience, improves communication skills, and—perhaps most importantly—fosters a relationship style that prioritizes mutual growth over possessiveness.
For many, open relationships aren’t just about exploring multiple connections—they’re about exploring themselves.
As open relationships continue to gain in popularity, more and more science is coming forward confirming what many of us already knew: Open relationships, when deployed properly via trust and communication, can greatly benefit relationships.
