I recently read an article about Ukrainian prisons using genital bondage to punish inmates. Prisoners who misbehave have their testicles and penis shackled or chained, sometimes metal chastity devices. It’s deliberately obvious, so as to humilate the inmate–it’s loud, heavy, and obvious you’ve been caught masturbating.The fascinating part is, more than half of the inmates subjected to this humiliating punishment become aroused when their genitals are locked up. I tried something similar on a recent prisoner of my own. The science bears out.
