What Is Unicorn Hunting?

Unicorn hunting describes a pattern where a couple — typically a heterosexual or bisexual man with a bisexual woman — searches for a third partner, usually a bisexual woman, who will join their relationship and be equally romantically and sexually involved with both of them. The word 'unicorn' refers to the target: someone who is genuinely bisexual, single, unattached, interested in both members of the couple equally, and willing to integrate into an existing relationship on the couple's terms. Finding this person is considered about as likely as finding a mythical creature. Why is it controversial? Several reasons, each with legitimate weight in the ENM community. First, the power asymmetry. The couple enters the search as an established unit with shared history, shared housing, shared social circles. The third person enters alone. The couple sets the terms. When the relationship faces stress, the couple often closes ranks — and the third person, lacking established individual relationships with either member, is the one who leaves. Second, the objectification concern. Unicorn hunting often treats the third person as a solution to the couple's needs (spicing up the relationship, addressing mismatched bisexuality, adding novelty) rather than as a full human being with their own needs and autonomy. Couples in search mode sometimes describe wanting a 'third' without demonstrating much interest in who that person actually is. Third, the 'couple privilege' problem. Existing partners naturally prioritize their established relationship, which makes genuine equity across all three connections structurally difficult. None of this means three-person relationships don't work. Functional throuples exist. The distinction is usually whether the third person entered with genuine equality — or whether the couple was 'unicorn hunting.'
