Sadomasochism (SM) is erotic play in which daydreams and fantasies are played out that have to do with power and sometimes pain. Other terms used for the same dynamic are erotic spanking, dominance & submission, guidance & surrender, bondage & discipline.
During a game one is dominant, while the other is submissive. Inflicting pain can be part of it. It’s a consensual activity, fulfilling the sexual desires of both partners. Both women and men can take the dominant role.
In a light form this can be experienced when a guy pushes a girl on the bed and keeps her wrists down, or when lovers bite or scratch each other. But it can also be an elaborate game in which talked about fantasies are enacted.
Various techniques may be used to put the submissive in a position of helplessness and the dominant in a position of authority, like bondage, blindfolding, inflicting pain and mind games.
