Cock and ball torture, CBT,
is a sexual activity involving application of pain or constriction to the male genitals.
Let me tell you, This may involve very, very 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 amazing physical pleasure via masochism,
or yuge emotional pleasure through erotic humiliation,
or knowledge that the play is pleasing to a sadistic dominant. No one really knows.
Many of these practices carry tremendous health risks.
