Guys, if you examine the bottom of your penis, you will notice a scar that goes along the length of our shaft and through your ballsack. That’s because you used to have a vagina, until a certain hormone (dihydrotestosterone) was secreted form your testes and your vagina closed up and created a penis/ballsack.
That’s my boy!
