CBT (Cock and Ball Torture)
CBT stands for cock and ball torture. It refers to a category of BDSM activities that involve pain, pressure, constriction, or intense sensation applied to the penis and testicles. CBT falls under pain play and often overlaps with sensation play, depending on how it is practiced.
The range of CBT is wide. On the lighter end, it includes gentle squeezing, flicking, light slapping, and temperature play with ice or warm wax. More intense forms involve ball stretchers, humbler devices, cock cages, weights, clamps, and targeted impact. Some practitioners also incorporate electrical stimulation through purpose-built devices. What counts as CBT for one person might be a warmup for another, so intensity is always relative to the individuals involved.
Safety Considerations
CBT sits at the intersection of pain play and edge play because the anatomy involved is genuinely vulnerable. Testicular torsion, nerve compression, and tissue damage are not hypothetical risks. They happen when people push too hard, too fast, or without understanding the anatomy.
A few non-negotiable principles: never apply heavy impact directly to the testicles. Avoid prolonged constriction that cuts off blood flow. Check circulation frequently when using rings, stretchers, or binding. If the receiver reports sharp, stabbing, or radiating pain (as opposed to the broad ache typical of CBT), stop immediately and assess. Review the health and safety guide before incorporating any form of CBT into your play.
Negotiation and Communication
CBT requires thorough negotiation before any scene. Both partners should be specific about which activities are on the table, what intensity levels are acceptable, and where the hard stops are. A traffic light system (green, yellow, red) works well for CBT because intensity can shift quickly. The person receiving CBT should never feel pressured to tolerate more than they are comfortable with, and the person giving it needs to stay attentive to nonverbal cues as well as verbal ones.
CBT is not something to surprise a partner with. It should always be discussed, agreed upon, and entered into with full, informed consent.
