Sado-masochism, often referred to as BDSM, involves the consensual exchange of power and the practice of giving or receiving pain for pleasure. It encompasses a variety of activities, including bondage, discipline, dominance, submission, and sadomasochism, where one partner takes on a dominant role while the other submits. The key elements are consent, communication, and safety, ensuring that all parties are comfortable and willing participants. It is a complex aspect of human sexuality that can enhance intimacy and trust between partners.
