Also called "sissification", feminization is a type of fetish where the focus is on a man (particularly androgynous men) crossdressing and being groomed into behaving more feminine. Is often done as either an act of humiliation, as the result of hypnosis, or to establish dominance (especially in femdom relationships). Some examples may even include medical alterations, like those caused by hormone therapy or more supernatural means, though it needs to be clear the character was originally male.
This term also applies to tomboyish girls being forced to act more conventionally feminine.
Note: do not tag all content specifically focusing on a male at birth character crossdressing or with gender-questioning themes as feminization.
