Self-bondage refers to the use of restraints on oneself for erotic pleasure. It is a form of erotic bondage which can be practiced alone.
Self-bondage is characterized by experimentation and ingenuity, and can be riskier than conventional bondage. Self-bondage requires use of techniques for self-binding as movement becomes increasingly restricted as more restraints are applied, and also requires a reliable release mechanism. Many types of bondage equipment can be applied before the one that restrains the hands. For example, leg irons can be applied, as well as gags, blindfolds, etc.
For many of its practitioners, the added challenges and dangers are a part of the appeal of self-bondage, who often devise elaborate self-bondage schemes and release mechanisms, both in practice and in erotic fiction.
Self-bondage is considered a higher-risk activity than many other BDSM practices — particularly when combined with autoerotic asphyxia — and has led to a number of recorded deaths. The death in 1994 of Stephen Milligan, the British Conservative MP for Eastleigh, was a case of autoerotic asphyxiation combined with self-bondage.
Self-bondage has all the risks of physical restraint and sexual bondage, with the added factor that should anything go wrong, there is no-one to effect a rescue. For example, if blood circulation cuts off sensation in limbs, the planned escape mechanism may not be usable.
Self-bondage can be either strict or sensual.
In sensual self-bondage, escape from restraints is simple and available immediately, if desired. For example, the keys might be within reach or the knots loosely tied. The chief aim is the sensation of immobility and of constrained movement.
