The most common type of fetish hookup is BDSM (bondage, discipline, dominance/submission, and sadomasochism). BDSM encompasses a wide variety of activities that involve the use of physical restraint and sensation play. This can include spanking, blindfolding, tying up with rope or restraints, and using toys such as whips or paddles. People may engage in this type of activity alone or with a partner(s).
