Joss Whedon's works, across all media including television, film, musicals, and comic books, are known for their commitment to gender and sexual equality. They have always encouraged their audiences to love whomever, and however, they wish. This book is a history of the sexualities represented in the works of Joss Whedon and it covers all of Whedon's genres, including fantasy, horror, science fiction, westerns, superhero stories, and Shakespearean comedy.

Unique for its consideration of the entire arc of Whedon's two-decade career, from the beginning of Buffy the Vampire Slayer's first season in 1997 through the conclusion of its twelfth (comic book) season in 2018, this book examines in detail both better-known queer sexualities of the LGBTQ+ spectrum, and lesser-known non-normative sexualities. The book includes chapters on Whedon's sexually dominant women and submissive men, sexual pluralism on Firefly, disabled sexualities in Whedon's superhero narratives, zoophilia in Buffy, queer and heteronormative sexualities in Dr. Horrible's Sing-Along Blog, the subversion of the sexual tropes of slasher films in The Cabin in Woods, and dominance and submission in Whedon's Much Ado About Nothing.
