Definition & Pronunciation

IPA:/baɪˈsek.ʃu.əl/Phonetic Spelling:by-SEK-shoo-uhl

Bisexual describes a sexual or romantic orientation involving attraction to more than one gender. A bisexual person may be attracted to people of their own gender and people of other genders.

The attraction does not need to be equal, simultaneous, constant, or expressed through relationships or sexual activity. A bisexual person may have stronger attraction toward one gender, experience attraction differently over time, or have dated only people of one gender.

Bisexuality concerns attraction, not indecision, promiscuity, relationship style, or the number of partners someone has had.

Easy Explanation

A bisexual person can feel sexual or romantic attraction toward more than one gender.

For example, someone may be attracted to women and men. Another bisexual person may be attracted to women and nonbinary people, or to people of several genders.

The prefix bi- traditionally means “two,” but modern bisexual communities often use the term more broadly to mean attraction to one’s own gender and other genders, or attraction to more than one gender.

Grammatical Formation and Usage

Bisexual is commonly used as an adjective:

  • She is bisexual.
  • He described himself as a bisexual man.
  • They discussed bisexual identity.
  • The organization supports bisexual students.

It may also be used as a noun:

  • She is a bisexual.
  • Bisexuals may experience discrimination.

However, bisexual person or bisexual people often sounds more person-centered.

The informal shortened form bi is widely used:

  • I am bi.
  • They came out as bi.

Bisexual and Bisexuality

Bisexual describes a person or identity.

Bisexuality is the noun referring to the orientation itself:

  • She is bisexual.
  • Her bisexuality is an important part of her identity.

Both terms concern patterns of attraction rather than a person’s current partner or relationship history.

What “Bi” Can Mean

Historically, bisexuality was often described as attraction to both men and women.

Many contemporary bisexual people define it more inclusively as:

  • attraction to more than one gender;
  • attraction to one’s own gender and other genders;
  • attraction regardless of a strict male-female division;
  • attraction in which gender may still influence the experience.

Definitions differ among individuals. A person’s own explanation of their identity should be respected.

Bisexual and Pansexual

Bisexual and pansexual may overlap, but they are not always identical.

Bisexual commonly means attraction to more than one gender.

Pansexual commonly means attraction to people of any gender or attraction in which gender is not a major determining factor.

Possible distinctions include:

  • A bisexual person may experience attraction differently according to gender.
  • A pansexual person may describe gender as having little or no influence on attraction.
  • Some people feel either label could fit but prefer one because of community, history, or personal meaning.
  • Some people use both labels.

Neither identity is more inclusive or valid than the other.

Bisexual and Biromantic

Bisexual generally refers to sexual attraction to more than one gender.

Biromantic refers to romantic attraction to more than one gender.

Sexual and romantic orientation may align, but they do not have to. A person might be:

These distinctions are especially useful for people whose sexual and romantic attractions differ.

Bisexuality and Current Relationships

A person’s current partner does not change their bisexual orientation.

For example:

  • A bisexual womandating a man is still bisexual.
  • A bisexual man dating another man is still bisexual.
  • A single bisexual person is still bisexual.
  • A bisexual person in a monogamous marriage remains bisexual.

Orientation describes capacity or pattern of attraction, not the gender of one current partner.

Attraction Does Not Need to Be Equal

Bisexual attraction does not need to follow a 50–50 pattern.

A bisexual person may:

  • usually feel more attraction to one gender;
  • experience romantic and sexual attraction differently;
  • notice changes in attraction over time;
  • feel attraction rarely or strongly;
  • have preferences without excluding other genders.

Unequal attraction does not make someone “less bisexual.”

Identity and Experience

Someone may identify as bisexual before having any romantic or sexual experience.

A person does not need to:

  • date more than one gender;
  • have sex with more than one gender;
  • prove equal attraction;
  • be in a relationship;
  • disclose the identity publicly;
  • use the label permanently.

Identity labels help people describe themselves, but individuals may change labels as their understanding develops.

Coming Out as Bisexual

Coming out means sharing one’s sexual orientation with others.

A bisexual person may come out to:

  • friends;
  • family members;
  • partners;
  • coworkers;
  • healthcare providers;
  • an online community.

Coming out is a personal decision, not an obligation. Safety, privacy, culture, religion, housing, employment, and family relationships may affect whether someone chooses to disclose.

Biphobia

Biphobia is prejudice, hostility, discrimination, or negative stereotyping directed toward bisexual people.

Examples include claims that bisexual people are:

  • confused;
  • going through a phase;
  • secretly gay or straight;
  • incapable of monogamy;
  • naturally unfaithful;
  • attracted to everyone;
  • seeking attention.

These stereotypes confuse orientation with personality, behavior, and relationship choices.

Bi Erasure

Bi erasure occurs when bisexuality is ignored, denied, or treated as unreal.

Examples include:

  • calling a bisexual person straight because they have a different-gender partner;
  • calling them gay because they have a same-gender partner;
  • excluding bisexuality from discussions of sexual orientation;
  • assuming everyone must be either heterosexual or homosexual.

Bi erasure can make bisexual people feel invisible within both heterosexual and LGBTQ+ communities.

Bisexuality and Monogamy

Bisexuality does not determine whether someone prefers monogamy, non-monogamy, casual sex, or long-term commitment.

A bisexual person may be:

  • monogamous;
  • polyamorous;
  • celibate;
  • casually dating;
  • married;
  • uninterested in relationships.

Being attracted to more than one gender does not mean needing partners of multiple genders at the same time.

Bisexuality and Gender Identity

Sexual orientation and gender identity are different.

A bisexual person may be:

  • a woman;
  • a man;
  • nonbinary;
  • transgender;
  • cisgender;
  • agender;
  • bigender;
  • another gender identity.

The person’s gender and the genders they are attracted to together shape how they may describe their orientation.

Respectful Language

Respectful communication includes using the label a person chooses and avoiding assumptions based on their current partner.

Helpful practices include:

  • saying bisexual person rather than treating the identity as a stereotype;
  • using bi only when the person is comfortable with it;
  • avoiding questions that demand proof of attraction;
  • not assuming bisexuality means availability;
  • respecting privacy about coming out.

Sexual orientation does not create consent or interest in any particular person.

Connection to Sexuality

Bisexual is directly connected to sexuality because it describes a pattern of sexual or romantic attraction involving more than one gender.

The identity may shape dating, relationships, self-understanding, community belonging, coming out, and the language someone uses to describe attraction. However, it does not determine sexual behavior, relationship structure, libido, or number of partners.

Respectful understanding of bisexuality recognizes diverse patterns of attraction, avoids stereotypes and bi erasure, and accepts that each person has the right to define, disclose, or privately understand their own orientation.
