A sex swing (also known as a sling) is a type of harness 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 buttocks, 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.
Hammock-style swings vary in the number of suspension points from three (two at the hips and one at the head), to four (two at the hips and two at the shoulders), to five (two each at hips and shoulders, plus one at the head). The functional difference between these variants lies in the stability of the sling when in use: the more suspension points, the less movement. However, many users prefer to have a greater range of movement.
Another variation is the sit swing, which holds the receptive partner upright in sitting position, rather than supine. Sit swings take most of the body's weight with large padded loops around the thighs, or some similar arrangement. Sit swings are commonly suspended from a single point attached to the ceiling, to a free-standing sex swing stand, or a door. Door swings offer quicker installation and lower cost, but sacrifice some flexibility.
The main purpose of sex swings is to make sexual intercourse more exciting and effortless. A sex swing may enable greater freedom of movement during intercourse or assist with challenging sex positions. Swings may be used for vaginal and anal sex, fellatio, and cunnilingus.
Sex swings can enable individuals with a physical impairment or disability to enjoy a wide range of sexual activities. Individuals with muscular weakness or arthritis may use a sex swing to reduce the strain on affected muscles or joints. Individuals who use a wheelchair can engage in sexual activity using a sex swing suspended from a hoist.[better source needed]
It is important to follow the provided instructions when using a sex swing. Secure mounting is vital to avoid injury to the suspended partner from falling. The use of toggle bolts, such as would be used to hang a dreamcatcher, is not appropriate. Installing springs, if supplied, is important to reduce physical shock to the suspended partner caused by rapid deceleration when bouncing in a sex swing.[better source needed]
