easy CBT device

I’m not certain if this has been posted before, but I discovered that securing a 2-liter bottle to a shoestring using a loop knot works well. Just slip the loop around your scrotum and let the bottle hang about 16 inches below it; gravity will take care of the rest. As the bottle hangs, it tightens up the testicles while also providing a gravitational stretch. You can combine this setup with parachutes or straps for the glans.
