Some people assume bisexuality is a phase and that people who say they are bisexual are really gay or straight. But bisexuality is a distinct sexual identity, different from gay or straight.

Hi! I’m here to help you explore what it means to be bisexual. It starts with the core element of attraction. In other words, who are you attracted to? Bisexuality is often misunderstood, but the more we learn, the more we understand that it is a sexual orientation all its own. And it has nothing to do with how we show up in the world, or the body we were born with. Let’s dig in...

(Adj.) An umbrella term for people who experience sexual attraction. A person who is allosexual can identify as gay, lesbian, straight, bisexual or any other sexual orientation. Learn More


(Noun) A feeling of interest in another person. Attraction can take different forms, including sexual, romantic, physical, emotional, and aesthetic attraction. Individuals may experience just one or multiple types of attraction for another person. Learn More


(Adj.) Refers to the sexual orientation of a person who experiences sexual, romantic, and/or emotional attraction to persons of more than one gender, not necessarily equally or at the same time, in the same way, or to the same degree. Also known as "bi". Distinct from pansexual, which refers to the capacity to be attracted to persons regardless of gender identity. Learn More


(Adj.) Describes the sexual orientation of persons who are emotionally, sexually, and/or romantically attracted to persons of the same sex/gender. While the term is most often used to describe men, it can also be used more broadly to refer to both men and women (i.e., gay man, gay woman, gay people). Learn More

Gender non-conforming (GNC)

(Adj.) Describes a person who does not behave in a way that conforms to traditional expectations for their gender, or whose gender expression does not fit neatly into a category. GNC does not mean non-binary and cisgender people can be GNC as well. Also known as gender variant. Learn More

Heterosexual / Heterosexuality

(Adj.) (Adj./Noun) Describes a primary or exclusive sexual, emotional, and/or romantic attraction to a gender other than one's own. Typically this means a woman who is primarily attracted to men and vice versa. Also referred to as "straight". Learn More

Homosexual / Homosexuality

(Adj./Noun) Describes a primary or exclusive sexual, emotional, and/or romantic attraction to one’s own sex/gender. The term is considered outdated by many in the LGBTQ+ community but is still used in some research contexts. Learn More


(Adj./Noun) Refers to the sexual orientation of women who are emotionally, sexually, and/or romantically attracted to women. Learn More


(Adj.) Describes the capacity to experience sexual, romantic and emotional attraction to an individual regardless of gender. Persons who identify as pansexual sometimes describe themselves as "gender blind"--that is, gender does not factor into attraction for them. More expansive than the term bisexual, which typically refers to attraction to more than one--but not necessarily all--genders. In fact, the prefix pan-, which comes from the Greek language, means “relating to the whole of the universe.” Learn More


(Adj) An umbrella term for persons who experience attraction to more than one gender. Identities such as bisexual, pansexual, and queer fall under this category. Learn more


(Adj.) Alternative term to LGBTQ+. An umbrella term for anyone who does not identify as heterosexual. Historically a negative term and insult, queer is being reclaimed by many LGBTQ+ people—particularly youth—as a source of pride and political identity. The term is valued by some for its defiance, by some because it can be inclusive of the entire community, and by others who find it to be an appropriate term to describe their more fluid identities. “Queer” is still disliked by some people in the LGBTQ+ community and its use by straight people can be considered offensive. Due to its varying meanings, this word should only be used when self-identifying or quoting someone who self-identifies as queer (i.e. “My cousin identifies as queer.”) Learn More


(Adj.)Describes the process of discovery and exploration about sexual orientation, gender identity, gender expression, or a combination thereof. Can be an aspect of adolescence as young people explore various facets of their identity.
Learn More


(Adj.) Drawn from the Greek lesbian poet Sappho’s name, sapphic is an inclusive umbrella term used to describe a woman or non-binary person of any sexual orientation (bisexual, lesbian, pansexual, or queer) who is attracted to other women. Learn More

Sexual identity

(Noun) The way a person views and understands their sexual orientation, such as gay, straight, bisexual, or some other orientation. Learn More

Sexual orientation

(Noun) Commonly used to refer to who we are or are not attracted to -- sexually, romantically, and emotionally--the relationships we have, and how we personally identify. Sometimes used more narrowly to refer to sexual attraction, behavior and identity. Attraction and behavior do not always define a person's sexual orientation. (e.g. a man who has sex with men may not identify as gay). Learn More


(Adj.) Another term for heterosexual. Refers to the sexual, emotional, and/or romantic attraction to a gender other than one's own. Typically this means a woman who is primarily attracted to men and vice versa. Learn More
