Sissification, observed within the BDSM and fetish communities, encompasses the journey undertaken by individuals, often cisgender males, as they embrace a transition geared towards embodying feminine characteristics, behaviors, and roles. This metamorphosis encompasses a range of activities meticulously crafted to feminize the person, catering to both physical and psychological aspects, thereby fulfilling fantasies associated with gender alteration and submission.

Throughout the sissification process, participants immerse themselves in diverse endeavors, including donning attire traditionally associated with the female gender, applying cosmetics, honing feminine mannerisms, assuming female personas, and engaging in role-playing scenarios that accentuate femininity. Furthermore, this journey may entail guidance on executing tasks and behaviors typically assigned to females, along with exploration of submissive roles within intimate relationships or BDSM dynamics.
