Definition & Pronunciation
The prefix bi- historically means two, but modern bisexual communities commonly use the term more broadly to mean attraction to more than one gender or attraction to genders similar to and different from one’s own. Bisexuality can include attraction to women, men, nonbinary people, transgender people, and people of other gender identities.
Bisexuality does not require equal attraction to every gender. Attraction may differ in intensity, frequency, emotional quality, or timing. A person may still identify as bisexual while single, celibate, married, monogamous, or dating a person of any gender.
Sexopedia Quick Reference
Bisexuality
Also Known As: bi, bisexual orientation
Note: Multisexuality is a broader umbrella category that includes bisexuality, pansexuality, omnisexuality, polysexuality, and related orientations.
Note: Monosexuality means attraction to only one gender. Asexuality involves little or no sexual attraction and is not a direct opposite in every classification.
Easy Explanation
For example, a bisexual woman may be attracted to women, men, and some nonbinary people. A bisexual man may experience attraction toward men and women. Another bisexual person may be attracted to people across several gender identities.
The attraction does not need to be evenly divided. Someone may feel attraction more often toward one gender while still being genuinely attracted to others.
Grammatical Formation and Usage
- She spoke openly about her bisexuality.
- Bisexuality is a valid sexual orientation.
- The article discusses bisexuality and pansexuality.
The adjective bisexual describes a person, identity, attraction, or experience:
- a bisexual person;
- bisexual attraction;
- a bisexual identity;
- bisexual representation.
It may also function as a noun:
- She identifies as a bisexual.
- The group includes bisexuals and pansexuals.
However, many people prefer person-centered wording such as bisexual person.
The informal shortened form bi is widely used:
- He identifies as bi.
- She is part of the bi community.
Word Formation
- bi-, traditionally meaning two;
- sexual, referring here to sexual attraction;
- -ity, forming a noun that describes an identity or state.
The historical prefix does not require bisexuality to be limited to only men and women. Language and community definitions develop over time, and many bisexual people define the orientation as attraction to more than one gender.
Bisexuality and Bisexual
- Bisexuality involves attraction to more than one gender.
Bisexual is the adjective or identity label:
- She is bisexual.
- He describes his orientation as bisexual.
The distinction is similar to:
- homosexuality and homosexual;
- heterosexuality and heterosexual;
- pansexuality and pansexual.
Bisexuality and Pansexuality
Pansexuality generally means attraction to people of any gender or regardless of gender.
The orientations overlap considerably. Some bisexual people are attracted across the full gender spectrum. Some pansexual people choose their label because gender does not strongly influence their attraction.
Compare:
- A bisexual person may say, “I am attracted to more than one gender.”
- A pansexual person may say, “Gender does not limit who I can find attractive.”
Neither label is more inclusive, modern, or valid than the other. Personal identity depends on which term feels most accurate and meaningful.
Bisexuality and Omnisexuality
Bisexuality is broader and does not specify whether attraction includes every gender or how gender affects the experience.
A person may choose bisexual because of its history, community, familiarity, or flexibility. Another may choose omnisexual because it communicates all-gender attraction more specifically.
Bisexuality and Polysexuality
Bisexuality means attraction to more than one gender and may include similar patterns.
The terms may overlap. Identity labels are not scientific measurements with perfectly fixed boundaries. People choose words that best communicate their experiences and community connections.
Bisexuality and Monosexuality
Examples may include:
Bisexuality involves attraction to more than one gender.
This distinction concerns the range of genders toward whom attraction may occur. It does not determine how often someone feels attraction, how strong it is, or whether they act on it.
Bisexuality and Romantic Orientation
A bisexual person may be:
- biromantic;
- panromantic;
- heteroromantic;
- homoromantic;
- aromantic;
- another romantic orientation.
For example, someone may experience sexual attraction toward more than one gender while experiencing romantic attraction mainly toward one gender.
Some people use the word bisexual broadly to include both sexual and romantic attraction. Others describe the two separately.
Attraction Does Not Need to Be Equal
Attraction may be:
- stronger toward one gender;
- more frequent toward one gender;
- romantic toward some genders and sexual toward others;
- influenced by personality or emotional connection;
- fluid or changing over time;
- difficult to measure precisely.
Unequal attraction does not make bisexuality less genuine.
Bisexuality and Gender Diversity
Transgender people are not a separate third category outside women and men. A transgender woman is a woman, and a transgender man is a man. Some transgender people are nonbinary or use another gender identity.
A bisexual person may be attracted to cisgender and transgender people of different genders. Attraction to transgender people is not limited to bisexual or pansexual orientations.
Bisexuality and Relationship Status
A bisexual person remains bisexual while:
- dating a woman;
- dating a man;
- dating a nonbinary person;
- married;
- single;
- celibate;
- in a monogamous relationship;
- in a consensually nonmonogamous relationship.
For example, a bisexual woman married to a man does not automatically become heterosexual. A bisexual man dating another man does not automatically become gay.
Bisexuality and Monogamy
A bisexual person may prefer:
- monogamy;
- consensual nonmonogamy;
- casual dating;
- long-term partnership;
- marriage;
- celibacy;
- single life.
Attraction to more than one gender does not mean needing partners of different genders at the same time. Faithfulness depends on behavior, values, and relationship agreements—not orientation.
Bisexual Erasure
Examples include:
- calling a bisexual woman straight because she dates a man;
- calling a bisexual man gay because he dates a man;
- treating bisexuality as a temporary phase;
- avoiding the word bisexual in media or history;
- assuming marriage ends bisexual identity.
This erasure can occur in heterosexual and LGBTQIA+ communities.
Biphobia and Monosexism
Monosexism is the broader belief that attraction to only one gender is more legitimate, stable, or understandable than attraction to multiple genders.
Common stereotypes may claim that bisexual people are:
- confused;
- indecisive;
- unfaithful;
- seeking attention;
- secretly gay;
- actually heterosexual;
- attracted to everyone;
- unable to commit;
- sexually available.
These ideas confuse orientation with personality, behavior, and relationship choices.
Respectful Language
- using the identity label a person chooses;
- not defining orientation through a current partner;
- avoiding invasive questions about sexual history;
- not demanding proof of attraction to multiple genders;
- rejecting stereotypes about infidelity;
- recognizing bisexual people in all relationship types;
- respecting changes in identity language;
- not treating bisexuality as confusion or experimentation.
A person does not need sexual experience with multiple genders to identify as bisexual.
Common Misunderstandings
Attraction may vary, and bisexuality is not limited to a strict gender binary.

They experience attraction selectively, like people of other orientations.
A current partner determines someone’s orientation.
One relationship does not reveal the full range of attraction.
Bisexuality causes infidelity.
Faithfulness depends on choices and agreements, not orientation.
Bisexuality excludes transgender or nonbinary people.
Many bisexual definitions explicitly include attraction across gender diversity.
Bisexuality is only a phase between straight and gay.

Connection to Sexuality
A bisexual person may be sexually active or abstinent, partnered or single, monogamous or nonmonogamous. They may experience attraction frequently, rarely, equally, or unevenly across genders. None of these differences makes the orientation more or less valid.
Bisexuality does not imply consent, sexual availability, promiscuity, or attraction to every person. Healthy sexuality requires communication, respect for gender identity, bodily autonomy, personal boundaries, and freely given agreement.
