Age Dysphoria

Stories in this category deal with characters whose body age doesn't match the internal age with which they identify. While most stories in this category involve someone with an adult body who feels like a child on the inside, any combinations of ages can be involved. Stories in categories such as "age regression" and "age progression" can be found at Big Closet Top Shelf.

In the BDSM community, people who present as children are commonly referred to as "littles" and their dominant partner will be a "Daddy" or "Mommy." Such relationships can be found within T* fiction as well.
