Feminization is when a person, usually a man, acts or dresses like a woman. This can involve wearing make-up, dressing in women's clothing, or adopting feminine mannerisms.
Some people enjoy combining feminization with BDSM activities, where one person takes on a submissive role and the other takes on a dominant role. The submissive partner may be feminized by their dominant partner as a way of increasing their humiliation or submission.
It's important to remember that all sexual activities should involve clear communication and consent between all parties involved.
