When you are having sex in the doggy position, the scrotum swings forward and hits the girl on the clitorus hence giving her a ballgasm.

What your crazy dog has when he/she is so focused on playing ball, (catch, fetch, keep away) that they completely ignore everything else: cats, food, sticks, etc.)
My dog Luna found a ball at the dog park today, and she's having a ballgasm - she won't let go of it, and even sleeps with it!
