Cock and ball torture (CBT) is a sexual activity involving torture of 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 – the recipient of such activities may receive direct physical pleasure via masochism, or emotional pleasure through knowledge that the play is pleasing to a sadistic dominant.
