Quotations
A slightly newer term, genderqueer […] is also often used by people who believe they are genderfluid, who feel like both genders, who will sometimes feel male, sometimes female, or who may not believe that there are only two genders.
2011, Ellen Greenblatt, Serving LGBTIQ Library and Archives Users, page 29
For example, "queer" would include self-identified lesbians and gays who also have sex with the "opposite sex," sexual practices and relationships that include kink, s/m, polyamory, and pansexuality, gender play and fuck including femmes and those feminine of center, butches and those masculine of center, queens, femboys, gurls, bois, sissies, tomboys, crossdressers, drag queens and kings, and genderfluid people.
