Bondage is the tying, binding, or restraining of a person for the sexual, aesthetic, and/or psychological pleasure of the parties involved.
Bondage features prominently in BDSM scenes and sexual roleplay. Bondage has a sexual appeal to people of both sexes and all sexual orientations, in either a dominant (top) or submissive (bottom) role.
Broadly speaking, bondage is any kind of physical restraint that restricts or controls someone’s movement.
For many, the arousal in bondage comes from the fantasy or act of being physically restrained or tied up. This is usually, but not necessarily, linked to submissive behaviour. For many people the bondage is a physical manifestion of a desire to give up control to another. The bondage can act as a permanent reminder to the bound person that they no longer control what is happening to them.
The sensations of being bound can also be arousing in their own right as it can stress the body and give the bound person something to struggle against. Bondage can also cause pressure on parts of the body which can be pleasurable (for example mummification).
