Fisting sling

A sex swing (also known as a sling) is a type of designed to allow sexual intercourse between one partner suspended by the swing and another who moves freely. Though there is considerable variety in the design, the most common sex swings have a support for the back, another for the , and stirrups for each leg, which can be adjusted whilst the user is suspended.

The following types of sex swing exist: traditional swing, door swing, body swing, and fantasy swing. The body swing is suspended from one partner's body. The door swing is mounted on a door. The fantasy swing is suspended from an eye bolt in the ceiling. In popular culture, sex swing is mostly associated with BDSM practices.

A sex swing or sling is designed to assist in sexual activity. Materials for constructing these devices include nylon webbing, heavy canvas,leather,neoprene, heavy rubber,wood,and steel. The designs provide access to the passive (receptive) partner's genitalia, perineum, buttocks, and anal areas while supporting the individual in a comfortable position, with the hips flexed, to allowing the passive partner to fully relax.

The most common sex swing is similar to a hammock and holds the receptive partner in a supine position (back down). A variant of the hammock style is a hanging platform of wood or metal, padded for comfort, on which the receptive partner reclines. The hanging platform differs from the hammock style in that, being rigid, the receptive partner's back is straight rather than bowed. Both the hammock and hanging platform designs are often equipped with loops or stirrups to support the ankles or calves up without the requiring exertion by the receptive partner. This allows the receptive partner's hips to be flexed without exertion, improving access to the areas of interest.
