Does it hurt to crush your manhood?
Set the timer to 5 minutes
ahaha I want you to put all your weight on the balls, then put your hands on your legs, and then try to keep your legs up.
Better if it spread out in front of you, but it is enough that they do not touch the ground and you do not support them anywhere.
After 5 minutes start bouncing on your balls.
Enjoy your 5 minutes of squeeze, and 2 minutes of bouncing!
