Bi-curiosity in a couple: how to talk about it calmly

Bi-curiosity comes up a lot in couples' private conversations and very little out loud. Someone mentions that a person of their own gender caught their eye, or that something unexpected stirred at a party, and suddenly the table is full of questions: "What does that mean?", "Are you bisexual?", "Where does that leave me?" This guide does not hand you a label. It helps you organise the conversation, understand what we actually know about sexual fluidity, and move respectfully if the topic reaches the swinger scene.

Bi-curiosity, bisexuality and fluidity are not synonyms

Three ideas often get blended together:

• Bi-curiosity: interest in, or curiosity about, people of a gender other than the one you usually feel attracted to. It does not have to become anything more, and it does not oblige you to call yourself anything.
• Bisexuality: attraction to more than one gender. It is an orientation, not a phase or indecision.
• Sexual fluidity: the idea that attraction or identity can shift over time or depending on context.

Researchers do not agree on everything either. A study in Archives of Sexual Behavior (2020) compared four different ways of measuring fluidity in women and found that they were mostly uncorrelated with one another: general erotic responsiveness to the less-preferred gender, situational variability, the gap between attractions and actual partnering, and day-to-day instability of attractions. Put simply, "fluidity" is not one thing, and one person's curiosity tells you little about their future.

Another number to keep things in proportion: a demographic analysis in Demography (2023) using US data reports that about 1 in 11 American adults changed sexual identity over five annual surveys (6% of cisgender men and 11% of cisgender women), with more movement among young adults and among people who had ever identified as bisexual. In other words, identity moving is neither rare nor pathological. It does not mean your partner is about to change either: these are population statistics, not a forecast for your home.

Why it is so hard to say

The curiosity itself is rarely the problem; the fear of what it implies is. Research on bisexuality describes stigma and, at the same time, disclosures that went well. A critical review of bisexual men's lives (Current Opinion in Psychology, 2023) reports widespread stigma but also positive experiences of coming out. A US probability-based study (Stigma and Health, 2023) found that stigma-related experiences and stress differed by partner gender and relationship status, a reminder that there is no single "bisexual experience".

Inside a couple, the fears tend to look alike:

1. "If I say it, my partner will think I no longer desire them."
2. "If I say it, they will ask whether I always knew and why I never told them."
3. "If I say it, I will have to do something about it."
4. "If my partner says it, it means I am not enough."

None of the four is true by default. Putting the fears on the table helps more than arguing about supposed intentions.

How to talk about it as a couple

Choose the moment. Not at 2 a.m., not after an argument, not with alcohol involved. A walk or a quiet dinner works better.

Start with what you feel, not what you want to do. "Lately I have noticed that..." opens far more than "I want us to try...".

Separate curiosity, fantasy and plan. A study in Archives of Sexual Behavior (2020) of 822 people in monogamous relationships found that almost a third (32.6%) included some form of sexually open relationship in their all-time favourite fantasy, and most of them (80%) said they wanted to act on it in future; those who had shared or acted on it generally reported positive outcomes. In other words, curiosity is more common than it looks, but what each person wants to do with it differs. Before discussing plans, check which of the three you are talking about.

Do not demand a label. If someone wants to call themselves bisexual, bi-curious or nothing at all, that is their call. Pushing someone to "define themselves" usually ends the conversation.

Ask what the other person needs. Safety, time, reassurance, knowing there will be no surprises. Our guide to bringing up swinging with your partner works here too: pace and listening are the same principles.

Accept that "I need to think about it" is a valid answer. Agree on a day to come back to it.

What research says about stigma and communication

A qualitative study in the Journal of Sex & Marital Therapy (2018) with 21 bisexual and plurisexual women with different-gender partners found they were selective about disclosing their involvement in consensual non-monogamy and apprehensive about stigma, and it highlighted communication as central. The sample is small and specific, but it illustrates something general: deciding who to tell, and when, is part of taking care of yourselves. We also have a piece on telling friends and family.

A more recent paper in Personality and Social Psychology Bulletin (2024) found that experienced stigma was associated with more psychological distress among people in consensually non-monogamous relationships, partly through anticipated and internalised stigma. It is an association, not proof of cause, but it is a good reason to choose carefully who you share this with and not to carry it alone.

If the topic reaches the swinger scene

Some couples discover their curiosity inside the lifestyle; others enter it with the curiosity already in mind. Some practical ideas:

• Talk before you go, not on site. Set your limits at home: what is a yes, what is a no, what only with a heads-up. Our piece on writing your agreements helps you put it on paper.
• Do not use the scene as an express therapy session. A club is not the place to settle a deep question or to surprise your partner.
• Respect each person's pace. A "no" or a "not yet" is accepted without explanation. Revisit club etiquette.
• Watch your language. Do not treat bisexual people as an "extra" or someone else's fantasy. They have their own lives, not a supporting role in someone else's night.
• Beware of pressure. If someone agrees only to avoid disappointing their partner, that is not full consent. Review consent, boundaries and signals.

Health and care

Widening the circle of people you are intimate with is a good moment to review sexual health habits. The World Health Organization notes that most STIs cause no symptoms and that safe, effective vaccines exist for hepatitis B and HPV. A Norwegian study (International Journal of Sexual Health, 2022) reported 3% of participants with consensual non-monogamy and condom use at the most recent extradyadic event of 21.5% among heterosexual men and 47.1% among gay and bisexual men, a reminder that protection should not be taken for granted. This is not medical advice; for tests, vaccines and schedules, talk to a health professional. More in sexual health in the lifestyle and in our testing calendar for open couples.

When you do not agree

Sometimes one person feels curious and the other does not want to go there at all. That does not make anyone a villain. Reasonable options: pause the conversation, find a therapist trained in relationship diversity, or accept that curiosity exists without a plan attached. A longitudinal Australian study in the Journal of Health and Social Behavior (2022) of young women found no universal link between changing sexual identity and psychological distress: distress rose when the change moved away from the heterosexual norm and fell when it moved toward it, social stress explained part of that effect, and women who stayed unsure across several waves reported more distress. The authors conclude that more support should be offered to people who are questioning. Applied to a couple: accompany, do not push.

Frequently asked questions

Does being bi-curious mean I am bisexual? Not necessarily. Curiosity can stay curiosity, and identity is something each person decides.

Has my partner stopped loving me if they feel curious about someone of their own gender? There is no evidence that one implies the other. Curiosity and love coexist.

Is it the same for men and women? Experiences and stigma vary by gender and context, as the studies above show, but the basis of the conversation (pace, no pressure and clarity) is the same.

Do we need to go to a club to explore it? No. Many people talk it through at home and never go. If you do go, do it with agreements made beforehand and without pressure.

Can I ask for professional help? Yes. Couples therapy from someone informed about sexual and relationship diversity can help; this guide does not replace it.
