CBT

Cock and ball torture (CBT) is BDSM play that applies controlled pain, pressure, or sensation to the penis and testicles for erotic effect. It's a broad umbrella covering ball busting (impact), clamps and clips, cock-and-ball bondage, stretching, squeezing, temperature play, and more. Because the genitals are so sensitive, sensation can be finely calibrated, which makes it a favourite tool for dialing a submissive's experience precisely up or down. It ranges from gentle teasing to genuinely intense torment. It's almost always done to a male submissive by a dominant partner.

The extreme sensitivity of the area turns even small stimulation into something powerful, and enduring it is a vivid act of submission and trust. For the dominant, holding the most vulnerable part of a partner under their control is an intense power exchange.

A dominant works through techniques — binding the cock and balls, applying clamps or a squeeze, light slapping or impact, stretching the scrotum — starting gentle and reading the submissive's responses closely, often on a pain scale, combined with teasing or denial.

Start light and build slowly; the testicles are genuinely injurable. Keep constant communication and a safeword, avoid sudden full-force blows, and don't cut off circulation with bindings for long. Stop and seek medical help for severe or lasting pain, swelling, nausea, or discoloration (signs of torsion or rupture), and avoid play when the area is numb.
