The short answer: in swinging, a unicorn is a single woman, usually bisexual or bi-curious, who plays with a couple, either with both partners or mainly with the woman. She is called a unicorn because so many couples are looking for her and so few actually exist, which makes her famously hard to find. Couples who go searching for one are known as “unicorn hunters,” a label that is sometimes affectionate and sometimes a warning.
If you are a couple thinking about adding a woman to your experiences, or a single woman wondering whether the role is for you, understanding the term (and the etiquette around it) will save you a lot of awkward conversations. Here is what it means, where the stereotypes come from, and how to approach it in a way that works for everyone involved.

Why Is She Called a Unicorn?
The name is a joke about supply and demand. Lifestyle dating sites are full of couples who say they want a single bisexual woman, but there are only a small number of single women who want that experience, and they are understandably picky. The result is a mythical creature everyone talks about and few people meet.
There is a second layer to the joke. Many couples who go unicorn hunting have a long wish list: she must be attractive, bisexual, equally into both partners, happy to leave when asked, never jealous, never wanting more. When you write all that down, you have described someone who sounds less like a real person and more like a fantasy. Experienced swingers use the word partly to gently remind couples of that.
What Unicorns Actually Want
Single women who enjoy playing with couples usually say the appeal is a mix of things: the chance to explore their attraction to women in a safe setting, the attention of two people at once, the absence of relationship pressure, and the reassurance of being with a couple who has clearly talked things through.
What they do not want is to be treated as a tool for someone else’s relationship. The most common complaints from unicorns are:
- Being contacted only by the husband, with the wife clearly not involved.
- Couples who have not agreed their own rules and start arguing mid-evening.
- Being expected to give equal attention to both partners on command.
- Being dropped or ignored the moment the couple is finished.
- Couples who want her to fix a struggling relationship.
If you are a couple, read that list carefully. Avoiding those five mistakes puts you ahead of most of the profiles she sees.
Why “Unicorn Hunting” Gets a Bad Reputation
In lifestyle and polyamory circles, “unicorn hunters” can be a criticism. It usually refers to couples who want a woman to fit neatly into their relationship without having any real needs or say of her own. Common examples include rules that she can only be with them together, can never contact one partner alone, or must have no feelings at all.
Rules are not the problem. Every good arrangement has them. The problem is when the rules only protect the couple and never consider the third person. A unicorn is an adult with her own boundaries and preferences, and the couples who get the best experiences are the ones who treat her that way from the first message.
How Couples Can Find a Unicorn the Right Way
If you are a couple hoping to meet a single woman, these steps make a real difference:
- Start with the woman in the couple. The idea should come from her as much as him, and she should be comfortable leading the conversations. Profiles where only the husband writes rarely get replies.
- Agree your own boundaries first. Decide together what is on and off the table, how you will handle jealousy, and what happens if one of you wants to stop. Our communication scripts for couples help with that talk.
- Be honest on your profile. Say clearly that you are a couple, what you are hoping for, and that you are happy to go at her pace.
- Meet for a drink first. Exactly like any first date, and without expectations. She is checking whether you are kind, relaxed and genuinely on the same page.
- Ask about her limits. Then respect them as carefully as you respect your own.
- Look after her afterwards. A message the next day, a thank you, and an honest chat about whether you would all like to meet again.
Unicorn Etiquette in the Moment
- Nobody gets left out by accident. Check in with each other during play; a quick look or word is enough.
- Use a safe word or signal that all three of you know.
- Protection and testing are agreed in advance, never negotiated in bed.
- The couple’s issues stay at home. If jealousy flares, pause politely and talk later rather than in front of her.
- Discretion is mutual. No photos without explicit agreement, and no sharing of names or details.
Tips for Women Who Want to Be a Unicorn
If you are a single woman curious about the role, you hold most of the power in this part of the lifestyle, so use it. Take your time choosing, talk to the woman in the couple directly, and ask both of them how they handle jealousy. Meet in public first, tell a friend where you are going, and leave if anything feels off. You do not owe any couple an explanation for saying no, and you are allowed to have feelings, preferences and rules of your own.
Many women start by attending a lifestyle event or club night with friends, where they can meet couples in a social setting with no pressure. Our guide to a first time at a swingers club explains what to expect.
Where Couples and Unicorns Actually Meet
Mainstream dating apps are a frustrating place to look; couple profiles are often reported or buried. Most people in the lifestyle use adult and lifestyle platforms where couples and singles are both welcome.
The biggest pool is AdultFriendFinder, the largest adult dating network, where couples and bisexual single women can search for each other directly (our AdultFriendFinder review for couples explains the filters). For a lifestyle-only, verified crowd, many swingers prefer SDC, the long-running lifestyle network, which also lists clubs and events.
Not ready to meet anyone yet? Plenty of couples explore the idea first by watching together. Real couples stream live on LiveMatures, our own house cam site (disclosure: we own it), which is a low-pressure way to see how each of you feels about a third person.
