I heard genitals can literally be pulled out by applying ONLY 20 lbs of force.
That’s the basic idea of hanging, and stretching! We’re trying to pull some of the “inner penis” out by stretching the ligs. At least, this is the goal when you are focusing your hanging or stretching on the ligs. We also attempt to lengthen the tunica as well. But for some guys it does take more than 20 lbs. force to pull the penis out.
