Bondage is the practice of tying, binding, or restraining a partner for erotic, aesthetic, or somatosensory stimulation. A partner may be physically restrained in a variety of ways, including the use of rope, cuffs, bondage tape, or self-adhering bandage. Bondage itself does not necessarily imply sadomasochism. It may also be used as a part of sex or in conjunction with other BDSM activities.
