Guy A "I just got anal with 5 different girls all at the same time!"
Guy B "INTESTICLES!"
Guy A "Oh, and your mom..."
A generalized pain "down there" that a horny guy feels when in the company of one or moreattractive females whom he'd like to be intimate with.
There is no known treatment/cure for intesticle distress, although the sharp aching and other more severe symptoms can often be dulled somewhat by totally "relieving the pressure" --- either by having a long period of hot 'n' heavy intercourse with someone or by simply "spanking the monkey" till you're completely "drained" --- right beforehand, so that your guy-junk will be totally weak and exhausted for a while, and so even a strong emotional desire for female flesh will not spur much if any embarrassing/awkward physical reaction between your legs while any of the desirable gals in question are in close proximity with you.
