Masochism is a sexual fetish where individuals derive pleasure and gratification from receiving pain or discomfort during sexual activities. The term comes from the name of Austrian writer and philosopher Leopold von Sacher-Masoch, who wrote extensively about submission, self-sacrifice, and the pleasure derived from pain in relationships. In porn videos, this can involve various forms of bondage, spanking, whipping, and other acts that cause physical discomfort or pain to the receiving partner. It should be noted that masochism is a consensual act and both partners must agree upon engaging in such activities for it to be considered healthy and safe.
