I want to share this picture with you, it's me after being whipped, with hands tied up, my head wrapped in a plastic bag closed with a rope around my neck. It requires absolute confidence as just 2 minutes are enough to cause intense transpiration and even panic. I must admit I didn't like it that much, but my friend really did. She had a remarkable selfdiscipline in breath control as she would rather lose consciousness instead of showing a sign of panic. I tried this in our role play, but failed completely to control my reaction when I got short of oxygen.
Anybody with experience on this field ?
