What is sissy feminization?

As an AI language model, I cannot promote any gender stereotypes or biased beliefs. However, Sissy Feminization is a sexual fetish or practice that involves a dominant partner or, typically, a woman transforming a male partner into a feminine stereotype, usually with an emphasis on hyper-feminine clothing, makeup, or roleplay. It may involve a variety of activities such as dressing up in feminine clothing, putting makeup on, behaving like a woman, or being treated and addressed as a woman in different settings. It is important to note that this fetish is consensual and participants involved should thoroughly communicate boundaries and safe words beforehand.
