In regards to sexuality, behavior refers to how a person interacts with others romantically or sexually. Along with attraction and identity, behavior is one of the 3 main components of sexual orientation.
Bi is a shortened form of bisexual and is often used as an identity label.
- Bi Erasure
Bi erasure is a tendency to ignore, remove, falsify, or reexplain evidence of bisexuality. Examples of bi erasure could include referring to all same-sex couples as "gay marriages,"; the active denial of the existence of bisexuality, or a history book ignoring or dismissing a figure's bisexuality and instead labeling them as gay or straight.
- Bi Umbrella
The bi umbrella refers to the fact that bisexual is a broad term for a sexual orientation. There are many identity labels that people may chose to use that fit under that umbrella.
- Bi Visibility
Bi visibility is about seeing and creating bi representation. Examples of bi visibility would be a person choosing to come out, wearing a bi shirt, having bi characters in media, or simply having bisexuality be a bigger part of the LGBT conversation.
A binary is a system that only has two parts, two possibilities. Whatever the topic, humans have a tendency to categorize people, ideas, and almost anything else as belonging to either group A or group B, in order to make the world easier to understand.
In regards to bisexuality, it is important to understand that the prefix "bi-" in bisexuality refers to having both same-sex and different-sex attractions. It is not in any way a commentary on the number of genders available in a society. Meanwhile, people's tendency to think of sexuality itself in terms of binaries is a major source of biphobia.
Biphobia is a dislike or prejudice against bi people and bisexuality. Its manifestations include the assumption that being exclusively attracted to members of a single sex is somehow more natural, real, or legitimate than being attracted to members of more than one sex. It can take the form of denial that bisexuality is a genuine sexual orientation, negative stereotypes about people who are bisexual, or bi erasure.
Bisexuality is a sexual orientation that describes people who have both homosexual and heterosexual attractions. Colloquially, this means attraction that is not limited by sex or gender.
