What is Monogamish?

by Kate Miller on Aug 10 2026

Monogamish: Monogamish describes a relationship that is mostly monogamous but allows specific, agreed upon exceptions for outside sexual contact, like a hall pass on vacation or a shared threesome.

Also known as: Semi monogamous, Mostly monogamous.

Monogamish is a word for couples who consider themselves committed and exclusive in almost every way, but who have carved out a small, clearly negotiated space for sex outside the relationship. It sits somewhere between fully closed monogamy and a wide open relationship. The exceptions are usually specific rather than open ended, things like a one time pass while traveling, a threesome the couple plans together, or flirting and kissing allowed at a party but nothing further.

If you have ever heard a couple say they are basically monogamous except for one rule they made together, that is monogamish in action. It is not about one partner sneaking around. It is about both people agreeing, out loud, on where the edges are. The word gives that arrangement a name, which makes it easier to talk about without borrowing language from fully open relationships that may not fit.

What Does Monogamish Actually Mean

At its core, monogamish means a couple's primary bond stays sexually and emotionally exclusive most of the time, with a small number of exceptions both partners have discussed and agreed to ahead of time. The exceptions can be as narrow as one specific event, like a bachelor party, or as ongoing as an occasional threesome the couple plans together a few times a year. What makes it monogamish rather than just monogamy with a lie in it is that both people know and consent.

The word does not describe a single fixed arrangement. Every monogamish couple sets their own boundaries. Some allow kissing but not sex. Some allow sex but only with strangers they will never see again. Some allow one partner more room than the other for reasons they have talked through. The common thread is honesty about the rule, not the specific content of the rule.

Where Did the Term Monogamish Come From

The word was popularized by sex advice columnist Dan Savage, who used it to describe his own long term relationship and the many couples who wrote to him with similar setups. He noticed that a lot of people did not fit neatly into either the fully monogamous box or the fully open box, and they needed language for the middle ground. Savage is a writer and columnist, not a researcher or clinician, so the term comes from cultural commentary rather than a scientific study.

Since then, monogamish has become a common shorthand in relationship writing and casual conversation. It does not belong to any one community or subculture. Straight, queer, married, and dating couples all use it, because the underlying idea, mostly closed with a few named exceptions, shows up across a lot of different relationship styles.

How Monogamish Relationships Work in Real Life

In practice, monogamish couples usually set rules around a few key questions. Who is allowed, is it a specific person, a type of person, or only strangers. What is allowed, does it stop at flirting, kissing, or go further. Where and when it can happen, maybe only on trips, only together, or only with advance notice. Answering these questions in advance is what keeps monogamish from sliding into confusion or hurt feelings later.

Many couples treat their agreement as something that can be revisited. What felt fine a year ago might not feel fine now, and that is normal. Life changes, feelings change, and a good monogamish agreement gets checked in on rather than treated as carved in stone. Some couples set a rule that any exception gets discussed again afterward, just to see how it actually felt versus how they thought it would feel.

Safer sex tends to matter more here, not less, because there is real contact with people outside the primary relationship. Couples who are monogamish often agree on condom use, regular testing, and being upfront about any new partners' sexual health. Consistent condom use and regular testing are generally understood to help lower the risk of STIs, though no method removes risk completely. A doctor or sexual health clinic can offer guidance on testing schedules and answer any questions about specific situations. Keeping these conversations open also helps keep trust intact between partners.

How to Talk to Your Partner About Going Monogamish

Bring it up outside the bedroom, when neither of you is upset or rushed. Frame it as curiosity rather than a demand, something like wondering out loud whether a small amount of flexibility might suit you both. Let your partner take time to sit with the idea instead of expecting an answer on the spot.

Get specific before you agree to anything. Vague rules cause the most pain later, so talk through who, what, where, and how you will tell each other about it. Agree on a way to check in afterward, even briefly, so feelings that come up have somewhere to go. If jealousy or insecurity shows up, that is not a sign you are doing it wrong, it is just information to work through together, possibly with the help of a couples counselor if it feels bigger than the two of you can sort out alone.

Is Monogamish Right for You

There is no single sign that monogamish is the right fit. Some couples land there because full monogamy feels a little too tight, and full non monogamy feels like more openness than either partner actually wants. Others try it after a specific event, like a bucket list threesome, and decide it works well enough to keep as an occasional thing.

It is worth being honest with yourself about your motives before you propose it. Wanting more variety together is a different starting point than trying to fix a problem in the relationship or please a partner who wants more room than you do. Monogamish tends to work best when both people genuinely want the arrangement, not when one person is going along with it to avoid conflict.

Types of Monogamish

Monogamish agreements vary a lot from couple to couple, but a few patterns come up often.

  • The one time pass: A single agreed exception, often tied to a trip, celebration, or milestone.
  • The shared experience: Outside sex only happens when both partners are present, like a threesome.
  • The boundary without sex: Flirting, kissing, or dancing with others is fine, but intercourse is not part of the agreement.
  • The occasional solo pass: One partner may have outside contact alone under specific, pre discussed conditions.
  • The don't ask don't tell version: Outside contact is allowed within limits, but details are not shared afterward, an arrangement that works for some couples and causes friction for others.

Key Things to Know

  • Monogamish means mostly monogamous with specific, agreed exceptions, so it is not the same as cheating because both partners know the rules in advance.
  • The term was popularized by columnist Dan Savage, which helps explain why it shows up so often in relationship writing rather than clinical literature.
  • Clear boundaries about who, what, and where matter more than the label itself, so vague agreements are the most common source of hurt feelings.
  • Safer sex practices matter more in monogamish setups because there is real outside contact, so testing and condom use are worth agreeing on upfront.
  • Agreements can and should be revisited over time, since what feels fine early on can change as the relationship does.

FAQ

Is monogamish the same as cheating?

No, the key difference is consent. Cheating happens without a partner's knowledge or agreement, while monogamish arrangements are built on both partners discussing and agreeing to specific exceptions ahead of time. If one partner is unaware or would object if they knew, it is not monogamish, it is a broken agreement.

Is monogamish the same as an open relationship?

They overlap but are not identical. Monogamish usually means mostly closed with a small number of specific, occasional exceptions, while an open relationship is built around ongoing non exclusivity as a regular part of how the couple operates. Think of monogamish as sitting closer to the monogamy end of the spectrum.

Do monogamish couples need to set rules in writing?

Writing things down is not required, but many couples find it helpful to at least say the rules out loud clearly and check that both people understood them the same way. Rules can be as simple as an honest conversation, as long as both partners feel clear and comfortable afterward. Revisiting the agreement occasionally helps catch any misunderstandings early.

What if jealousy comes up in a monogamish relationship?

Jealousy is a common and normal response, even in couples who both agreed to the arrangement. It usually helps to talk about the feeling openly rather than push it aside, and to slow down or adjust the agreement if it keeps coming up. If jealousy feels overwhelming or does not ease with communication, a couples counselor can help you both work through it.

Can any couple become monogamish?

Most couples can consider it, but it works best when both partners genuinely want some flexibility rather than one person agreeing just to keep the peace. It also depends on how well the couple communicates, since the whole arrangement relies on honesty and clear boundaries. If trust is already shaky, adding outside contact usually makes things harder, not easier.
