What Is Ethical Non-Monogamy? Polyamory, Open Relationships and Swinging, Explained

It’s an umbrella term covering three quite different arrangements, and almost every argument about it comes from people using the same word for different things.

What Is Ethical Non-Monogamy? A Plain Definition

Ethical non-monogamy, usually shortened to ENM, is any relationship where more than two people are romantically or sexually involved and everybody has knowingly and freely agreed to it. The word doing the work is ethical, and it carries more than most people assume.

Four things have to be true, and all four at once.

• Everybody knows. NOTHING is happening in secret, and nobody is being managed with half the picture.
• Everybody actually understands what they’ve agreed to. Which model it is, what the boundaries are, what counts as sex. A yes to something you haven’t had explained isn’t a yes.
• Nobody was pushed into it. Not by pressure, not by an ultimatum, not by the fear of losing somebody if they said no. Agreement given to keep the peace isn’t agreement.
• Anybody can change their mind. This is the one people leave out. Consent here isn’t a signature on day one, it’s an ongoing conversation, and a partner who wants to slow down, pull a boundary back in or close the whole thing again has to be able to say so without punishment.

That last point isn’t theoretical. Later on this page I’ll tell you about a couple who ran an open relationship successfully for thirty-five years, and what happened when one of them changed their mind.

So no, it’s not a lifestyle, a personality type or a political position. It’s an AGREEMENT, and an agreement everybody is still free to renegotiate.

The Three Models People Constantly Confuse

ENM is an umbrella. Underneath it sit three arrangements that work very differently, and Victoria says the first job of any couple considering this is figuring out which one they’re actually talking about.

• Polyamory. Multiple close romantic relationships. You’re opening yourself up to feelings and attachments with more than one person.
• Open relationship. The couple does things separately. Each partner goes on their own dates, the arrangement sometimes nicknamed a “hall pass.”
• Swinging. The couple does things together, with other people or other couples. They don’t go off separately.

Almost every disagreement I’ve watched about this comes from one partner picturing polyamory while the other pictures swinging. They aren’t having the same conversation. Naming the model out loud, early, heads off most of it.

There’s one principle running through all three, and it’s the community’s own, not any one person’s: go as fast as the slowest-paced person. No pushing, no rushing, nobody talked past their own comfort.

What Makes It “Ethical”: The Agreement, Not the Arrangement

Here’s what surprised me most. There is NO rulebook. Victoria was clear that no community-wide code exists. The rules are different from one couple to another, and each couple writes their own.

What she does see is a pattern in how those rules evolve. Newcomers arrive and build a lot of them, long lists and tight fences, and then over time couples become more fluid as they become more secure. She gave her own example: she and her husband started out agreeing not to see the same people twice, and that rule ended pretty quickly once they’d made friends they wanted to see again.

Her advice on rule-making is worth borrowing whatever your relationship looks like.

1. Talk through as many hypothetical situations as you can in advance.
2. Accept that you’re guaranteed to be surprised anyway, and act on the best information you have in the moment.
3. When something goes sideways, have the conversation and adjust the agreement for next time.
4. Have grace and forgiveness. Your partner did their best with the information they had.

That last one isn’t specific to non-monogamy at all. I’d hand it to every married couple I know, and it belongs on any honest list of what a healthy relationship looks like.

What Counts as Cheating in an Open Relationship

This is the question I hear most from people outside the community, usually phrased as a gotcha. How can you cheat if everything’s allowed?

Victoria’s answer is precise. Cheating here means breaking an agreed boundary in secret. She gave the example: someone says they’re going on a date with another man’s wife and instead goes off and has a secret threesome. That ended the marriage. Having more than one partner, when that’s the agreement, is not cheating at all.

So the line isn’t the number of people. The line is honesty about what was agreed. Strip away the arrangement and the definition of betrayal is identical to the one in any monogamous marriage: you said one thing, did another, and hid it. If concealment is already a feature of your relationship, the red flags were there long before this conversation came up.

What Counts as Sex, and Why You Settle It First

This one made me sit up, because it applies to absolutely everybody and almost nobody does it.

I read the standard definitions out on air, from the dictionary and from ChatGPT, and they cover intercourse in any form, oral sex, mutual masturbation, with both people acting with sexual intent. Some people count deep kissing. Others don’t.

Victoria’s response was that sex is whatever someone thinks it is. For her it involves penetration of one kind or another. Oral or foreplay on its own she doesn’t count. She was quick to add that a lesbian couple’s definition might be completely different from hers, and that’s exactly the point.

Which means it has to be settled beforehand, out loud, so there aren’t any misunderstandings. Two entirely honest people can discover six months in that they’d been using the same word for different things the whole time.

And I’d put that conversation on the list for monogamous couples too — it belongs right alongside the conversation before intimacy. I’ve had more than one client find out, months in, that what she’d been calling an emotional friendship, he’d been calling an affair.

What About Jealousy?

It doesn’t disappear. Nobody in this community claims it does. People who grew up with monogamous expectations arrive carrying a lot of possessiveness, and Victoria describes it in exactly those terms: don’t even look at him, he’s all mine.

What experienced couples describe instead is a slow rewiring toward compersion, which is joy at a partner’s pleasure with somebody else.

I’m going to leave it there, because jealousy deserves more room than a subheading. I’ve written the whole thing up separately, including a tool one couple I know extremely well uses to shut the spiral down in about ten seconds, and how compersion actually gets built. It’s here: how to handle jealousy.

How to Raise the Subject With a Partner

Victoria’s approach, for anyone wanting to open this conversation with someone new:

• Don’t lead with it. Her own example of how not to do it: you’re talking about friends and family and core values and all of a sudden it’s “so what do you think about swinging?”
• Plant little conversational seeds. A show you saw, a meme, a reel. You’ll learn a great deal before you’ve committed to anything.
• If they’re wary, ask what specifically worries them. Not salesy, she says, more like working through the objections. Offer information, not pressure.
• Have the conversation before sex, not after. Her reasoning is straightforward: afterwards you’ve got those chemicals in your brain and you feel more connected, which is precisely the wrong condition for a clear-eyed decision.

I’ll add my own rule, and I apply it to every serious relationship conversation there is. Have it in the light of day, without drinking and without anything else on board, and have it early. Not at midnight. Not the day after a misunderstanding you’re now trying to repair backwards.

The Practical Side Nobody Mentions: Testing, Money and Bedrooms

The romantic conversation gets all the attention. The logistics are what people actually trip over.

Sexual health. Victoria describes the community as unusually conscientious. Couples in the lifestyle are often getting tested every three or four months, and discussing results is treated as an ordinary, low-drama topic. Her own comparison was blunt: she’d feel safer in that respect inside the community than with someone met out in the wild at a bar. Barrier protection gets negotiated in advance with new people rather than improvised.

Money. More relationships means more money. Gifts, dates, holidays, birthdays, in multiples. And there’s a specific friction she flagged: if the husband has girlfriends and is spending significantly on them while the wife has chosen to stay monogamous, resentment builds fast, and it sounds like you should be spending that amount on me. The common solution she sees is two separate accounts plus one joint. Personal money stays personal, shared obligations come out of the joint account.

Bedrooms. The most practical detail of all, and the one nobody expects. Many couples keep separate bedrooms, each one made into its own little cave by whoever sleeps in it. Partners can visit without anybody feeling their bed sheets are being shared out, and in ordinary day-to-day life the couple still has sleepovers in each other’s rooms.

What It Actually Looks Like Day to Day

Everything above comes from a matchmaker. Here’s what it sounds like from somebody living in it.

Misty O’Hara came on the show to talk about her novel, The Hundred Man Plan, and stayed to describe her actual household. She’s been married to her husband for thirty-one years. Nineteen of those years were monogamous. Now she, her husband and her boyfriend of seven years all live in the same house, her husband has had a girlfriend of three years, and the two men, who are both IT directors, get on perfectly well.

She’s fifty, she has three grown children, and they didn’t tell the kids until the youngest turned twenty-one. The kids’ response was more or less: mom, you accept our unconventional lives, obviously we accept yours.

What I want you to take from Misty isn’t the arrangement. It’s her honesty about the parts that are hard. She has jealousy, she says so plainly, and she’s simply found a way to break it down when it shows up. When her husband does something sweet for his girlfriend that he hasn’t done for her lately, there’s a sting, and she handles it by asking herself not to be a hypocrite, because she’s certainly done things for her boyfriend she hasn’t done for her husband.

Her core position is that there’s no single right way to love, and she doesn’t believe in one soulmate per person. People divorce, people are widowed, people fall in love again, and she thinks that’s fine and normal. She also says a small share of the world lives this way, and she’s careful to note she’s not certain of the number, which is more intellectual honesty than most people bring to the subject.

Is Monogamy Still Realistic?

I put a version of this to Elizabeth Ashford, the founder of Beyond the Bees, on a different episode, and her answer is the one I’d want a monogamous couple to take away from this whole article.

Monogamy works beautifully for a great many people. What isn’t healthy, she says, is the version where people shut down the idea that anyone else exists, where you can’t so much as say a person is beautiful. The healthier version creates an energy where you’re reminded that you are choosing each other, and that concept of choice brings action. It’s what makes people keep working at it.

She also pointed me to Esther Perel’s The State of Affairs, which she calls one of her favorite reads on infidelity. Not a book that lets anybody off the hook, she says, but one that helps you heal if you’re the person going through it.

I’ll offer a caution from my own files. I know a couple who ran a completely transparent open relationship for thirty-five years. The deal was you can, I can, but never without transparency.

It ended, and not because of the openness. It ended because after thirty-five years she simply didn’t want to do it anymore.

Neither monogamy nor non-monogamy is a fixed structure. People change, so the agreement has to be allowed to change too — and sometimes the change is the end.

If you’re rethinking what your own structure should look like, my piece on rethinking marriage sits right next to this one.

Who This Works For, and Who It Doesn’t

Victoria was refreshingly unsentimental here, and her warnings are the most useful part of the conversation.

Don’t open a relationship to fix one. You shouldn’t come into this community with relationship issues already, she says. Being in these spaces expedites whatever needs to happen. Either you sink or you swim.

Expect it to end in one of several ways. She sees couples where one partner loses interest and the other continues, with everybody content. Couples who go monogamous for a while, for as long as it feels right. Couples who close permanently and stay together, including one who later had a baby, and when Victoria asked whether she was glad she’d had the experience, the answer was yes, because it opened up their communication. And couples who separate.

The gender math is upside down from what everybody assumes. In conventional matchmaking I’m always short of men. In Victoria’s practice more men tick the non-monogamous box than women, so her female clients are easy to place and her male clients face heavy competition.

And the standards are higher, not lower. This is the assumption she spends most of her time correcting with male clients. A lot of men think that because these women are non-monogamous, they’re easy. In fact the standards are HIGHER, because the women are unusually well informed about themselves, about what they’re looking for, about consent and about reading body language. Where men lose is on craft: they don’t think their profile matters, they don’t think their photos matter, and they’re very quick to try to steer the conversation to sex. Her guidance is to court, to compliment, to tell stories, and to let her broach that subject when she’s ready.

Which is exactly what I’ve been telling men in my thoroughly monogamous practice since 1990. Some things don’t vary by arrangement.

I’ll tell you what changed my mind about putting this on my site at all. When I opened my agency in Los Angeles in 2001, the questionnaire had four boxes for marital status. Single, divorced, widowed, married. That was IT, and I wrote it myself and thought it was thorough.

Victoria’s intake asks about relationship dynamic, about demisexuality and asexuality and heteroflexibility, about non-binary as a gender option, which she personally pushed the certifying body to add. Twenty-four years, four boxes to forty. I don’t think that’s decline. I think it’s people finally being allowed to say out loud what was always true.

And I’ve got a practical stake in it. My clients are largely in their fifties and sixties, and what a woman of fifty-eight wants from a match is NOTHING like what she wanted at twenty-six. When she asks me about an arrangement I don’t personally practice, I would rather give her a straight answer than a blush. That’s all this page is.
