Impact play is a human sexual practice in which one person is struck usually repeatedly by another person for the gratification of either or both parties which may or may not be sexual in nature. It is considered a form of BDSM. In erotic spanking the sub is struck on the buttocks either with the dom 's open hand, or a rigid implement such as a paddle , cane or riding crop.
In the latter case the activity is often referred to as paddling , caning or cropping. In erotic flagellation the sub is struck with a flexible implement such a whip or belt. Whips are classified by how many falls they have:. For safety, impact play should be done on areas of the human body well protected by fat or muscle; spots to avoid include the kidneys, neck, tailbone, hipbones, the head and all joints. The usual targets for flagellation are the buttocks and the two areas of the upper back below the shoulder blades.
With care, the thighs, the backs of the calves and the chest can be targets as well. Breasts are another potential but high-risk target, and should only be used with experience. The use of a whip means that the dom must take great care to hit the intended target area, and avoid wrapping ; when a whip or flogger makes contact with the target area somewhere up its length and the remaining length wraps around the sub's body to deliver a sharp, non-erotic, and possibly injurious off-target blow, such as to the hipbones or ribs.
The longer the falls, the more skill is required by the Dom to land a safe blow. Advanced flogging techniques use a pair of floggers employed in a martial arts style alternating pattern, a technique commonly referred to as "florentining" or "florentine flogging. Less common forms of impact play include punching and face slapping. A slapper or smacker may also be used. This consists of a broad 3 to 4 inch wide semi flexible leather paddle with rounded and tapered edges, designed to minimize the severity of tip strike.
The sensations produced by impact play depend on the area in which the impact is concentrated. Wide implements such as an open hand, paddle or flogger produce a dull "thuddy" sensation. Narrow implements such as a cane, riding crop, belt or single tail produce a sharp "stingy" sensation. One of the earliest depictions of erotic flagellation is found in the Etruscan Tomb of the Whipping from the fifth century BC, named after its depictions of eroticized flagellation.
