Open Marriage: What It Is, Risks and Questions to Ask Before Considering It

Last updated October 22, 2026 by the Marriage Bliss Editorial Team.

An open marriage is a marriage in which both spouses agree that one or both may have sexual or romantic relationships with other people, with clear rules they’ve negotiated together. What separates it from cheating is full knowledge and enthusiastic consent from both partners. Some couples find it works for them, and many find it hard. It isn’t a fix for a struggling marriage, and nobody should feel pressured into it.

This guide explains in plain, non-explicit terms what open marriage means, why some couples consider it, the risks and trade-offs, questions to ask before deciding, how to handle it if your spouse raises it and when to seek professional support. It takes no moral position on how couples should arrange their marriages. It’s general information, not therapy or medical advice.

At a glance

• Defined by consent: both partners knowingly and freely agree. Secrecy is cheating, not openness.
• Not a repair tool: it tends to magnify existing problems rather than solve them.
• It takes work: communication, boundaries, honesty and emotional management are essential.
• It’s okay to say no: declining isn’t a failure, and it doesn’t make you uptight or unloving.

Is this normal?

People arrange their relationships in different ways, and some couples do choose openness. But hearing that your spouse wants one can be deeply unsettling, and it’s reasonable to feel shocked, hurt, curious or conflicted. If you’re the one raising it, it’s reasonable to feel nervous. Whichever side you’re on, you deserve to be heard. See also micro-cheating and signs of an emotional affair for how trust boundaries are usually understood.

Open marriage and related terms

• Open marriage: spouses agree each may have other relationships, often with rules.
• Ethical non-monogamy: an umbrella term for relationships where everyone involved knows about and consents to multiple partners.
• Swinging: couples sharing experiences with others together, usually as a recreational activity.
• Polyamory: multiple committed romantic relationships, with everyone’s knowledge.

These arrangements differ a lot, so couples need to define exactly what they mean.

Why couples consider it

• Curiosity, or a desire for variety.
• A belief that one person can’t meet all needs.
• Mismatched desire, which they hope to resolve. See sexless marriage.
• A wish for honesty about attractions rather than secrecy.
• Personal philosophy about relationships.
• A way to avoid a divorce, or a history of infidelity. This is the riskiest reason.

His side, her side

The spouse who raises it: “I’m not trying to hurt you or leave. I want to be honest about something I’ve been thinking about, and I’m afraid of your reaction.”

The spouse who hears it: “I feel shocked and scared. Does this mean I’m not enough? I don’t know whether I’m being asked, or told.”

Whichever you are, the first task is to listen. Neither of you should decide in the first hour.

Risks and trade-offs

• Jealousy and insecurity. Even with agreement, strong feelings can appear unexpectedly.
• Unequal desire. One partner may want it far more than the other, and the arrangement may feel lopsided.
• Emotional attachment. Feelings can develop that weren’t planned for.
• Broken rules. Rules that are bent or hidden damage trust. See lying in marriage.
• Health. Any additional partners raise sexual health considerations. A doctor can advise on testing and protection.
• Impact on family and community. Children, relatives, work and social circles may be affected.
• Time and energy. Managing relationships takes effort.
• Irreversibility. Some experiences can’t be undone, and couples who try it sometimes find it changes the marriage permanently.

Questions to ask before deciding

1. Why do we each want this, or not want it? What would we hope to get?
2. How would we feel if it hurt? What would we do?
3. Is our marriage solid enough now, with good trust and communication?
4. Are we considering this to solve a problem, such as a lack of intimacy or past infidelity?
5. What rules would protect each of us, such as honesty, protection, limits on time, people we know or emotional involvement?
6. What are our deal-breakers, and what happens if one of us wants to stop?
7. How will we handle jealousy and check in regularly?
8. How do we protect our children, our privacy and our health?
9. Could we try a trial period, with a clear review date?
10. If we disagree, are we both prepared to accept that the answer may be no?

If your spouse raises it

1. Take time. You don’t have to decide, and you can say you need to think.
2. Say how you feel, honestly, without insults.
3. Ask questions. What led to this? Is there something missing? Has anything already happened?
4. Don’t agree to avoid conflict or fear of losing the marriage. That isn’t consent. It’s pressure.
5. Set your own boundaries. “No” is a complete answer. You can also say “not now” or “I’d consider it with conditions.”
6. Get support. A counselor can help each of you. See our marriage counselor guide and discernment counseling.

If you’re the one raising it

• Choose a calm time and say it plainly and kindly.
• Don’t present it as a done deal or a threat.
• Accept “no” without punishing your spouse.
• Be honest about whether anything has already happened. If it has, that’s a different conversation. See how to get over infidelity.
• Be prepared for a strong reaction, and give your spouse time.

What to say (and what not to say)

Try:

• “I’d like to talk about something that’s hard to say. I want to hear how you feel, and I don’t expect an answer now.”
• “I’m not comfortable with this. Can we talk about what’s underneath it?”
• “I need time to think. Please don’t take my silence as a yes or a no.”

Avoid:

• “If you loved me, you’d agree.” / “If you won’t, I’ll find someone anyway.”
• Going ahead in secret.
• Mocking or shaming your spouse’s reaction.
• Making rules that only apply to one person.

When it’s a bigger problem

Seek help if:

• One partner is pressured, threatened or coerced into agreeing, or is being controlled in other ways. That isn’t consent. Contact the National Domestic Violence Hotline at 1-800-799-7233, text START to 88788, or chat at thehotline.org. Call 911 in an emergency.
• The idea has come up after infidelity, or you’re considering it to save a failing marriage. A counselor can help you look at the underlying issues. See should I stay after infidelity? and should I get a divorce?
• You or your spouse feel distressed, anxious, depressed or hopeless. Talk to a therapist or doctor, and call or text 988 in a crisis.
• Sexual health is a concern. A doctor can advise on testing and protection.

Frequently asked questions

What is an open marriage?

It’s a marriage in which both spouses knowingly agree that one or both may have other sexual or romantic relationships, with rules they’ve set together.

Can an open marriage save a struggling marriage?

Counselors generally caution against it. It tends to magnify existing problems rather than solve them, so the marriage’s foundation matters first.

What if my spouse wants an open marriage and I don’t?

You’re entitled to say no. Take time, talk honestly about what’s underneath, and consider counseling. Agreeing out of fear isn’t consent.
