A Little is a person who regresses to a younger age. This age varies from little to little and some littles can regress to various ages. At one point they may be two and interested in diapers and breast feeding while later they could be fourteen and interested in a “sex education scene.”



A Big is a person that counters the little and acts as the adult or older person in the scene. This person could take on various roles from mommy or daddy to aunt or uncle to big brother or sister. Some scenes could involve a nanny or babysitter as well.



Neither the role of the Little or the Big is by definition a submissive or dominant role, unlike those roles in other fetish or kink scenes like Master and slave or Owner and pet. A Little could be the dominant of the Big or submissive to a Daddy-Dom or Mistress-Mommy and dominant to a brother or sister.



Just as neither role is dominant or submissive in nature, neither role is limited by gender either.



Sissification, the feminization of a man, is also done in age play. Many male age players enjoy regressing to a young age and being treated, dressed and acting like a little girl rather than a little boy. This is commonly done with frilly dresses, wigs, girl-specific toys, and even make-up to make a man look more like a girl. For some, this allows them to act out desires they had as a child that they felt were too taboo or that they would have been in trouble for. Other men use sissification in an age play scene as a form of humiliation, which is consented upon just as the age play is.



Women also can change gender in an age play scene and act and are treated like a little boy. This form of age play simply doesn’t have a specialized terminology that is commonly used.
