BDSM stands for bondage, discipline, dominance, submission, sadism, and masochism. It involves consensual acts that explore power dynamics, role-playing, and various forms of physical and psychological stimulation. Some common BDSM practices include bondage, spanking, flogging, role-playing, and sensory deprivation. It's important to establish clear boundaries, use safe words, and prioritize consent and communication between all parties involved.
