This is for the on-going battle about penis being a muscle that revenger must fight all by himself. The penis is NOT a muscle. It enlarges due to the blood being pumped into 3 sponge like structure of the shaft of the penis. ok so why is it that you can control the excretion of urinating or jizz is its not volunteer muscle control? You are actually controlling other muscles that make sphinters contract or relax in your genitals.

Thanks to Youtube and videos like this there is no way anyone should be failing biology, anatomy, or physiology in this day and age.
This video explained to me in 3 minutes what I had trouble understanding after reading a whole chapter. And it wasn't even painful.
Beautiful job whoever produced this.
