S&M, or Sadomasochism, is a practice within the broader realm of BDSM that involves the consensual exchange of power and the experience of pain or humiliation for pleasure. Participants may take on dominant or submissive roles, where one person derives pleasure from inflicting pain or humiliation, while the other finds enjoyment in receiving it. Safety and consent are crucial in S&M activities, often established through clear communication and the use of safewords. This ensures that all parties involved are comfortable and aware of their limits, promoting a healthy and respectful environment for exploration.
