f you’ve ever heard someone say “we’re non-monogamous” and found yourself nodding politely while silently Googling under the table—don’t worry, you’re not alone. Ethical Non-Monogamy (or ENM for short) is an umbrella term that covers a lot of different relationship structures—and yes, it can be confusing at first!
The good news? You don’t need a PhD in relationship dynamics to understand it. Whether you’re ENM yourself, partnered with someone who is, or just curious about how people are loving outside the monogamy box, this post is for you.
Let’s break down some of the most common ENM relationship structures in a way that makes sense—and maybe even makes you smile.
1. Open Relationships – “You do you, and I’ll do me… respectfully.”
Open relationships are often what people picture first when they hear “non-monogamy.” In an open relationship, a couple agrees they can have sexual (and sometimes emotional) connections with others outside their primary partnership. There’s usually some level of agreement around what’s okay and what’s not (think: who, how often, whether to share details, etc.).
It’s not a free-for-all—respect, honesty, and boundaries are key.
2. Polyamory – “Love isn’t limited, and neither are we.”
Polyamory means having—or being open to—more than one loving, emotionally intimate relationship at the same time, with everyone involved being aware and consenting.
Some polyamorous folks have a “primary” partner and other “secondary” or “tertiary” partners. Others practice “non-hierarchical” polyamory, where no relationship is ranked above the others. Communication and scheduling skills? Critical. Google Calendar? Basically a love language.
3. Relationship Anarchy – “Let’s define everything ourselves.”
Relationship Anarchy (RA) challenges the idea that romantic or sexual relationships should automatically be more important than friendships or other types of connection. RA folks tend to reject traditional scripts and prefer to build relationships based on mutual consent, freedom, and individuality.
It’s kind of like saying, “We don’t do boxes here.”
4. Swinging – “Party time, excellent!”
Swinging often involves committed couples who consensually engage in sexual experiences with others, usually in social or party settings. This can be one-time encounters or ongoing arrangements, but it’s usually more about recreation than deep emotional connection.
Swinging tends to be more structured, and it often comes with very clear boundaries—plus, there’s probably a theme party involved.
5. Solo Polyamory – “I’m the center of my own universe.”
Solo poly folks enjoy multiple relationships but don’t typically have a primary partner or merge lives with others (like sharing finances or living together). Think of it as polyamory with a strong sense of independence and autonomy.
They may love deeply—but they don’t necessarily want a “nesting partner” or a traditional relationship escalator.
So... Why Does This Matter?
Even if you’re not practicing ENM, chances are you know someone who is—or you will. Understanding different ENM relationship structures helps create more inclusive, compassionate communities. And if you are ENM, it’s empowering to know that there’s no “right” way to do this—just the way that works for you and your partners.
Every structure has its own strengths and challenges. Some people thrive with lots of fluidity. Others need more structure and agreements. What matters most is that everyone involved feels safe, heard, and valued.
A Note From the Therapy Couch 🛋️
Navigating ENM can bring up big feelings—jealousy, insecurity, communication breakdowns… or even just confusion about what you want. That’s okay! Therapy can be a helpful space to explore your relationship style, process emotions, and build stronger relational skills—solo or with partners.
