just a quick question (i dunno whether anyone has asked it before) but why does it hurt so much when guys get hit in the stones? if its an evolution thing then why didnt we evolve bones protecting them, and why doesnt our head hurt so much when it is hit?

Yer “boys” are exposed because sperm needs to be produced at a temperature slightly below normal body temperature. This is not only why they are external, unlike the ovaries in the female, but also why they sit closer to your body in cold weather, and further away when it’s warmer. Encasing them in bone, etc would defeat the purpose.

Sorry, ol’ son: yer stuck with that particular vulnerability.
