Sissy-bitch is a term used in the context of BDSM and fetish pornography, typically referring to a submissive male partner who takes on a feminine or subservient role during sexual activities. This type of role play often includes elements of humiliation, cross-dressing, and other forms of gender play. In essence, it is a label for a man who willingly assumes a more passive and submissive position in BDSM dynamics.
