Unicorn hunting, done better

A “unicorn” is a single bisexual woman willing to join an existing couple. The name reflects how rare that combination of interest and availability is relative to how many couples are looking for it.

Why it gets a poor reception

Not because the arrangement is inherently objectionable — plenty of people enjoy it. The complaints are about how couples typically go about it, and they are consistent enough to list.

• Treating her as an accessory. Profiles that describe what she must provide, with no acknowledgement that she is a person with preferences of her own.
• Rules made without her. Rules she is expected to follow, agreed entirely between the couple, presented as non-negotiable.
• No equal footing. She can be dismissed at any point by either of them; she has no equivalent power.
• The one-penis policy. Requiring exclusivity from her while the couple retains full freedom.
• Using her to test the relationship. Bringing someone in to see whether the couple can handle it, without telling her that is what is happening.
• Volume. The sheer number of couples messaging means her inbox is full and her standards are correspondingly high.

The maths problem

There are far more couples seeking this arrangement than there are women seeking it. That imbalance is the whole reason the term exists, and it means the burden of being interesting falls entirely on the couple.

It also means most couples' approach — a short message, a generic profile, an assumption of availability — has essentially no chance. She has fifty of those.

Doing it better

1. Write to her as a person. Reference her profile. Ask what she is looking for before explaining what you want.
2. Let her set terms too. If she has boundaries that conflict with your rules, that is a negotiation rather than a disqualification.
3. Do not require bisexuality by default. A great many couples specify it without thinking about whether it matters to them.
4. Meet as three people. Coffee, all of you, no expectations. Not an audition.
5. Be honest about the shape of it. If this is a one-off, say so. If you are hoping for something ongoing, say that instead.
6. Treat a decline as final. Immediately.

The honest self-check

One question sorts most of this out: if she wanted to see one of you without the other, or wanted to stop seeing you both, would that be allowed?

There is no obligation to say yes. But if the answer is no in both directions, you are asking for a level of commitment from her that you are not offering back, and that asymmetry is what people are objecting to when they use the term dismissively.
