In Sexual Subcultures
Sissy takes on more specific meanings in the transgender (though not considered transgender by many transgendered people), infantilist, and BDSM communities (especially through forced feminization or petticoating practices).
In the BDSM practice of forced feminization, the male bottom undergoing cross-dressing may be called a sissy as a form of erotic humiliation, which may elicit guilt or sexual arousal, or possibly both, depending on the individual.
In (paraphilic) infantilism, a sissy baby is a man who likes to play the role of a baby girl.
