Petticoating refers to a type of fantasy role play that involves a submissive man being coerced into dressing in female clothing. This practice is said to have originated as a form of punishment in Victorian times although it may have come about even earlier. Only recently has this practice taken hold within a sexual sphere.
Petticoating enthusiasts enact this in order to achieve sexual arousal and often engage in the practice with the aid of a dominant female figure who aims to humiliate them.
This term is also used to describe a subgenre of erotic literature that involves this practice.
Petticoating is sometimes referred to as pinaforing, pinafore eroticism, or pinafore.
