CBS News has been running a lot unappetizing stories about sex lately. First it was "Things You Didn't Know About Your Penis" (or "Four Things I Already Knew About Your Penis And One That Grossed Me Out"). Then there was "Top 10 Reasons To Have Sex Tonight" (or "10 Terrible Reasons to Have Sex Tonight.") Instead of waiting for CBS to produce their inevitable list of factoids about testicles, we made our own. After the jump, five terribly important facts about balls.

  • Erections Can Hurt Balls
     Prolonged sexual arousal can cause a temporary fluid congestion in the testicles. Known as "blue balls," this is unpleasant.
  • Erections Make Balls Harder
     When blood is flowing to that region, testicles become firmer.
  • Balls Emit A Slight Odor
     To prevent this, shower regularly.
  • There Should Be Two
     Something is wrong if there is only one.
  • Hair Grows There
     Don't feel bad if your balls are hairy. They're supposed to be! Unless of course you're encouraging a specific activity.
