When it comes to testicles, rule #1: You cannot apply heat directly on the testicles.
I've made my balls A LOT more hung and much bigger within a few weeks.
1) Take a very warm bath
2) While you're laying down in the steaming water, let your penis get warmed up. Your balls get heated also BUT it is safe to take a HOT bath. The exchange of heat from water to testicles IS NOT the same as rice sock to testicles. The heat emitted by the rice sock penetrates the skin much better. Besides, men are designed for heat. Our testicles drop in the bath. Taking a bath isnt supposed to be bad for you. Were made this way. Taking a warm bath twice a week wont make you sterile. Applying rice sock will!
3) If you have a water pump, go ahead and pump your cock in the warm water.
4) at the end of your pump routine, get out of the bath and dry yourself
5) your testicles will be extremely hung low because your body temperature is high
6) Lightly give little pulls on your scrotum. When you get accustomed to this, you can pull a little harder with time.
7)
never pull on the actual testicle. This will damage the spermatic cord. The spermatic cord supplies blood into the testicles, and it pulls the blood OUT of the testicles. If you damage this structure, you may develop many serious health issues such as varicoceles.
