Welcome to the flavors of gay:
Asexual: A person who generally does not feel sexual attraction or desire to any group of people. Asexuality is not the same as celibacy.
Ally: Typically any non-LGBT person who supports and stands up for the rights of LGBT people, though LGBT people can be allies, such as a lesbian who is an ally to a transgender person.
Androgyny: (1) a gender expression that has elements of both masculinity and femininity; (2) occasionally used in place of “intersex” to describe a person with both female and male anatomy
Closeted: a person who is keeping their sexuality or gender identity a secret from many (or any) people, and has yet to “come out of the closet”
Coming Out: the process of revealing your sexuality or gender identity to individuals in your life; often incorrectly thought to be a one-time event, this is a lifelong and sometimes daily process; not to be confused with “outing”
Cross-dressing: wearing clothing that conflicts with the traditional gender expression of your sex and gender identity (e.g., a man wearing a dress) for any one of many reasons, including relaxation, fun, and sexual gratification; often conflated with transsexuality
Drag King: a person who consciously performs “masculinity,” usually in a show or theatre setting, presenting an exaggerated form of masculine expression, often times done by a woman; often confused with “transsexual” or “transvestite”
Dyke: a derogatory slang term used for lesbian women; reclaimed by many lesbian women as a symbol of pride and used as an in-group term.
Faggot: a derogatory slang term used for gay men; reclaimed by many gay men as a symbol of pride and used as an in-group term
FTM/MTF: a person who has undergone medical treatments to change their biological sex (Female To Male, or Male To Female), often times to align it with their gender identity; often confused with “trans-man”/”trans-woman”.
Biphobia: Aversion toward bisexuality and bisexual people as a social group or as individuals. People of any sexual orientation can experience such feelings of aversion. Biphobia is a source of discrimination against bisexuals, and may be based on negative bisexual stereotypes or irrational fear.
Bisexual: A person who is attracted to both people of their own gender and another gender. Also called “bi”.
Gay: A person who is attracted primarily to members of the same sex. Although it can be used for any sex (e.g. gay man, gay woman, gay person), “lesbian” is sometimes the preferred term for women who are attracted to women.
Genderless: a person who does not identify with any gender
Hermaphrodite: an outdated medical term used to describe someone who is intersex; not used today as it is considered to be medically stigmatizing, and also misleading as it means a person who is 100% male and female, a biological impossibility for humans
Heterosexism: behavior that grants preferential treatment to heterosexual people, reinforces the idea that heterosexuality is somehow better or more “right” than queerness, or ignores/doesn’t address queerness as existing
Heterosexual: a medical definition for a person who is attracted to someone with the other gender (or, literally, biological sex) than they have; often referred to as “straight”
Homosexual: a medical definition for a person who is attracted to someone with the same gender (or, literally, biological sex) they have, this is considered an offensive/stigmatizing term by many members of the queer community; often used incorrectly in place of “lesbian” or “gay”
Hypersex(ual/-ity): an intensified sexual attraction.
Heterosexual: A person who is only attracted to members of the opposite sex. Also called “straight."
Homophobia: A range of negative attitudes and feelings toward homosexuality or people who are identified or perceived as being lesbian, gay, bisexual or transgender (LGBT). It can be expressed as antipathy, contempt, prejudice, aversion, or hatred, may be based on irrational fear, and is sometimes related to religious beliefs.
Intersex: A person whose sexual anatomy or chromosomes do not fit with the traditional markers of "female" and "male." For example: people born with both "female" and "male" anatomy (penis, testicles, vagina, uterus); people born with XXY chromosomes.
In the closet: Describes a person who keeps their sexual orientation or gender identity a secret from some or all people.
Lesbian: A woman who is primarily attracted to other women.
Queer: 1) An umbrella term sometimes used by LGBTQA people to refer to the entire LGBT community. 2) An alternative that some people use to "queer" the idea of the labels and categories such as lesbian, gay, bisexual, etc. Similar to the concept of genderqueer. It is important to note that the word queer is an in-group term, and a word that can be considered offensive to some people, depending on their generation, geographic location, and relationship with the word.
Pansexual: A person who experiences sexual, romantic, physical, and/or spiritual attraction for members of all gender identities/expressions, not just people who fit into the standard gender binary (i.e. men and women).
Sexual orientation: The type of sexual, romantic, and/or physical attraction someone feels toward others. Often labeled based on the gender identity/expression of the person and who they are attracted to. Common labels: lesbian, gay, bisexual, pansexual, etc.
Transgender: This term has many definitions. It is frequently used as an umbrella term to refer to all people who do not identify with their assigned gender at birth or the binary gender system. This includes transsexuals, cross-dressers, genderqueer, drag kings, drag queens, two-spirit people, and others. Some transgender people feel they exist not within one of the two standard gender categories, but rather somewhere between, beyond, or outside of those two genders.
Transphobia: The fear or hatred of transgender people or gender non-conforming behavior. Like biphobia, transphobia can also exist among lesbian, gay, and bisexual people as well as among heterosexual people.
Transsexual: A person whose gender identity is different from their biological sex, who may undergo medical treatments to change their biological sex, often times to align it with their gender identity, or they may live their lives as another sex.
Pansexual: a person who experiences sexual, romantic, physical, and/or spiritual attraction for members of all gender identities/expressions
Skoliosexual: attracted to genderqueer and transsexual people and expressions (people who aren’t identified as cisgender)
Third Gender: (1) a person who does not identify with the traditional genders of “man” or “woman,” but identifies with another gender; (2) the gender category available in societies that recognize three or more genders
Transitioning: a term used to describe the process of moving from one sex/gender to another, sometimes this is done by hormone or surgical treatments
Trans-man: a person who was assigned a female sex at birth, but identifies as a man; often confused with “transsexual man” or “FTM”
