Stories of people or beings who for whatever reason or circumstance dress or live, or want to, not as the gender they were assigned at birth, et cetira.
Fictional stories about characters who"magically" change genders or can gender shift also count. But only IF the gender bender premises isn't just done for sexual comedy and the like.

Gender bending also applies if the story or a character/s seeks to define gender expression outside of the binary terms of male and female, or aren't physically male or female, et cetira.
Biographies and memoirs that are written in storybook formats (e.g The Childhood of Famous Americans series) can be listed as well. Click the link below to go to a non fiction Gender-Bender and crossdressing list.
