Erotic spanking is the act of spanking another person for the sexual arousal or gratification of either or both parties. It is considered part of BDSM. It may involve very light and brief spanking or much more extensive spanking, including the use of implements such as whips or paddles. Activities range from a spontaneous smack on bare buttocks during a sexual activity, to occasional sexual roleplay, such as ageplay, or domestic discipline and may involve the use of a hand or a variety of spanking implements, such as a spanking paddle or cane. Erotic spankings are commonly combined with other forms of sexual foreplay. The most common type of erotic spanking is administered on the bare buttocks. For safety, erotic spanking should take care to avoid the tailbone and hipbones.
