“Ball-busting” is a form of CBT in which a man has his testicles kicked, kneed, punched or squeezed. In addition to its occasional role in BDSM pornography, Tamakeri (玉蹴り) (lit. ball-kicking) is a separate genre in Japan. Like many of the other activities in this article, it carries significant health risks, including the possibility of permanent damage to the testicles through testicular trauma.
