Why do our balls hang of us in a sack? Why can't they be inside the penis?
I mean, everything else is already inside of you. Why couldn't our balls just be inside the penis instead of being in a sack flailing about that is so easily vulnerable to physical harm?

That's something I wondered myself a couple of times. I mean the balls are one of the most important part of a male body but they just hang there and can easily be destroyed. I know it is because the body heat would kill all the sperm but still nature kinda screwd us over.
