Lesson 2: Stroking
Stroking the penis without sexual release is another form of cock torture. It builds the pressure in the prostate. It also builds blood pressure in the genitals. The pressure is quite uncomfortable. The pressure in the testicles alone is referred to as blue balls. Over long periods of time such as several hours the blood pressure can cause cell damage because fresh oxygenated blood is not reaching the area. Never under-estimate the torture method of just stroking. Usually the man is forced to stroke his own penis.
