Blue Balls is a painful outcome of being denied an orgasm despite constant arousal. Many believe Blue Balls can only happen if you are strictly cut off at point of
ejaculation. This is untrue, Blue Balls can happen even if you have had no stimulus in
the penis. This may be
the cause of early onset Blue Balls but no study confirms that. Blue Balls can happen at any state of arousal as long as it is continuous.
Blue Balls can happen while you are out with a person who is sexually appealing. Though there is a lot of erotic stimulus (kissing, cuddling, groping, etc) there is no actual penile stimulus, Blue Balls will onset and stay until an ejaulation can occure.
E.G. "We made out for hours but she didn't want sex, so I went home and on
the drive my nuts HURT!! Like hurt to touch and every
bounce on the road...."

Damn dude, Blue Balls suck man!"
