The last time we ran into Alex and Xander — the twin brothers behind the Science of Sin video series — they explained to us why falling in love is like smoking meth. This time around, they reveal everything you’ve ever wanted to know about testicles, like “Why are they shaped like pecans?” and “What would happen if I lost them them?”
Turns out that if you cut the testicles off a boy, as he ages he’ll gain less muscle, less body hair and his voice will remain high. On the upside though, losing your balls early on can also ensure that you never go bald and you live about 14 years longer. Balls, THEY’RE A DEADLY KILLER!
But if castration’s not your thing, Alex and Xander also solve the mystery of why one ball usually hangs lower and why they retract into a guy’s body right before cumming — sexcellent!
