Cock and ball torture (CBT) is a sexual activity involving application of
pain or constriction to the male genitals. This
may involve directly painful activities, such as wax play, genital spanking, squeezing,
ball-busting, genital flogging, urethral play, tickle torture, erotic electrostimulation or even kicking.
1 The recipient of such activities
may receive direct physical pleasure via masochism, or emotional pleasure through erotic humiliation, or knowledge that the play is pleasing to a sadistic dominant.
