Bondage and discipline

Bondage and Discipline are two aspects of BDSM that do not necessarily relate to one another, but can appear jointly. The term "Bondage" describes the practice of restraining for pleasure. Bondage is usually, but not always, a sexual practice. While bondage is a very popular variation Within the larger field of BDSM, it is nevertheless sometimes differentiated from the rest of this field. Studies among BDSM practitioners in the U.S. have shown that about half of all men find the idea of bondage to be erotic; many women do as well. Strictly speaking, bondage means binding the partner by tying their appendages together; for example, by the use of handcuffs or by lashing their arms to an object. Bondage can also be achieved by spreading the appendages and fastening them with chains to a St. Andrews cross or spreader bars.

The term "Discipline" describes the use of rules and punishment to control overt behavior in BDSM. Punishment can be pain caused physically (such as caning), humiliation caused psychologically (such as a public flagellation) or loss of freedom caused physically (eg. chaining the Bottom to the foot of a bed). Another aspect is the structured training of the Bottom. Overlap with practices from the field of bondage can occur, but is not necessarily mandatory. A differentiation between bondage and discipline is sometimes difficult.
