The short answer: an open marriage is a marriage in which both spouses agree that one or both of them can have sexual or romantic experiences with other people. The key word is agree. It is not cheating, because nothing is hidden: the couple sets the rules together, stays honest about what happens, and can change or close the arrangement at any time. Open marriages come in many forms, from a one-off hall pass to swinging together to each partner dating separately.
Interest in open marriage has grown as more couples talk openly about non-monogamy, but the term still causes confusion. Some people picture a marriage falling apart; others picture a nonstop party. The reality for most open couples is far more ordinary: two people who love each other, who have decided that sexual exclusivity is not the thing holding their marriage together, and who put a lot of work into communication. This guide explains what an open marriage is, the main types, the rules couples use, and how to bring the idea up with your spouse.
Open Marriage Meaning: A Simple Definition
An open marriage is a form of consensual non-monogamy. Both partners know about and agree to the arrangement, and both have a say in its rules. That separates it from an affair, where one partner is deceived, and from a marriage that has quietly fallen apart, where nobody is setting any rules at all.
Three things are present in almost every healthy open marriage:
- Consent from both spouses, given freely and revisited over time.
- Agreed boundaries, covering who, what, where and how much each partner wants to know.
- Honesty, both between the spouses and with any other adults involved.
Types of Open Marriage
“Open marriage” is an umbrella term. These are the most common arrangements under it:
| Type | What it looks like | Learn more |
|---|---|---|
| Swinging | The couple plays together with other couples or singles, usually at the same time and place | Hotwife vs swinger |
| Hotwife | The wife has experiences with other men, with her husband’s full support and involvement | What is a hotwife? |
| Stag and vixen | Like a hotwife setup, but the husband enjoys it from a confident, sharing angle | Stag and vixen vs hotwife |
| Dating separately | Each spouse can meet other people independently, within agreed rules | See the rules below |
| Hall pass | A one-time or time-limited permission rather than an ongoing arrangement | What is a hall pass? |
| Polyamory | Ongoing romantic relationships with more than one person, not only physical ones | Often the most emotionally involved form |
Some couples are open in only one direction, for example a hotwife arrangement where only the wife sees other people. That is still an open marriage, as long as both spouses genuinely want it. A one-sided setup should be a shared choice, never a concession one partner makes reluctantly.
Open Marriage vs Cheating
The physical acts can look the same, so the difference is entirely about consent and honesty:
- In an open marriage, your spouse knows, agreed in advance, and helped set the rules.
- In cheating, your spouse does not know, or the agreed rules are being broken.
That last point matters. An open marriage can still involve cheating if one partner breaks the agreement, for example by seeing someone who was ruled out or hiding a date. The rules only work if both people keep them.
Why Couples Choose an Open Marriage
Every couple has their own reasons, and many have more than one. The ones we hear most often from readers include:
- Different levels of desire between partners who otherwise work well together.
- A shared fantasy, such as a husband who is turned on by his wife’s confidence with other men.
- Curiosity and variety after many years together, without wanting to leave the marriage.
- A belief that love does not require exclusivity, often discovered through reading or friends in the lifestyle.
- Feeling more connected, not less. Many open couples describe compersion, the warm feeling of being happy that your partner is enjoying themselves.
One reason that rarely works: opening the marriage to fix a relationship that is already in trouble. Non-monogamy tends to amplify whatever is already there, good or bad.
Common Open Marriage Rules
There is no universal rulebook, but most open couples agree on some version of the following. Our list of 10 rules every couple should set before starting goes deeper.
- Who is allowed. Many couples rule out friends, coworkers, exes and neighbours.
- What is allowed. Some couples are fine with dating and kissing but not sex, or with sex but not sleepovers. The soft swap vs full swap distinction is a useful starting vocabulary.
- How much to share. Some partners want every detail; others prefer a “don’t ask, don’t tell” approach. Decide in advance.
- Protection and testing. Agree on condoms, testing and how often, and stick to it without exception.
- Time and priority. Your marriage comes first. Protect date nights and family time from new connections.
- A veto or pause button. Either partner can ask to slow down or stop, and the other respects it.
- Regular check-ins. A short, honest conversation after every new experience keeps small issues small.
How to Bring Up an Open Marriage With Your Spouse
This is the conversation most people dread. A few things make it go better:
- Pick a calm moment, not right after an argument, in bed, or after a few drinks.
- Talk about the fantasy or the feeling first, not a specific person. “I’ve been curious about what an open marriage would be like for us” lands better than naming someone.
- Make it clear you are not unhappy with them. Your partner’s first fear is usually that they are not enough.
- Ask, then listen. Their first reaction is not their final answer. Give them time and expect more than one conversation.
- Accept “no”. If your spouse is not interested, the idea goes back on the shelf. Pushing turns a fantasy into a wedge.
If you want help finding the words, our communication scripts for couples include openers and responses you can adapt. Some couples also watch real couples together on LiveMatures, our own house cam site (disclosure: we own it) as a low-pressure way to see how each of them reacts before any real-world step.
Where Open Couples Meet People
Once you both agree, the next question is where to look. The answer depends on your type of open marriage. Couples who play together tend to use lifestyle communities like SDC, which also lists clubs and parties. Couples who date separately, or a hotwife looking for a single man, usually get the most choice on a large network like AdultFriendFinder, where married and partnered members are completely normal.
We compare all the main options, including Feeld and OkCupid, in our guide to the best open relationship apps. Whichever you choose, be honest in your profile that you are married and that your spouse knows.
Signs an Open Marriage Is Working (and Signs It Is Not)
It is usually working when you both look forward to check-ins, jealousy comes up but gets talked through, the rules feel like they protect you rather than restrict you, and your own relationship feels as close as before or closer.
It is usually not working when one of you keeps bending the rules, one partner feels pressured or left behind, secrets start creeping in, or the time and attention going outside the marriage keeps growing. Closing an open marriage, temporarily or permanently, is a legitimate choice and not a failure.

Open Marriage FAQ
What is an open marriage in simple terms?
It is a marriage where both spouses agree that one or both of them can have sexual or romantic experiences with other people, under rules they set together. Because both know and agree, it is not cheating.
Is an open marriage the same as swinging?
Swinging is one type of open marriage, where the couple usually plays together. Other types include hotwife arrangements, dating separately, hall passes and polyamory.
Can an open marriage be one-sided?
Yes. In a hotwife or stag and vixen arrangement, only the wife sees other people. It works when both spouses genuinely want that setup, not when one partner simply tolerates it.

They can, for couples with strong communication, real enthusiasm from both partners and clear rules. They tend to struggle when used to fix existing problems or when one partner feels pushed into it.
How do you ask your spouse for an open marriage?
Choose a calm, private moment, start with the feeling or fantasy rather than a specific person, reassure them that you are not unhappy with them, listen to their reaction, and accept a “no” gracefully.
Is an open marriage legal?
In most places, an open marriage is a private agreement between consenting adults. Some jurisdictions still have old adultery laws on the books, and divorce rules differ, so if you have a specific concern where you live, check the local law or ask a lawyer.
