Bondage is a sadomasochistic practice which consists of attaching one's partner in the context of an erotic or sexual relationship. Appearing for the first time as a practice recognized as such during the 20th century in several countries, bondage is based on a certain number of fantasies that it stages, and which can refer to ancient tortures, such as as bondage techniques used in Japan (hojōjutsu), or such as different forms of crucifixion. In addition to the ropes used to tie up your partner, bondage uses all kinds of means of restraint.
