In my experience, an appropriate reaction to rejection does not normally entail the removal of body parts, testicular or otherwise. However, it has reinforced the view that a man cannot say no to sex - you could lose your balls.
I just realised how much of an ogre i am, by reacting like everybody else with disgust and 'ouch' thought, only to realise Dewey my dog led near me without any balls and its my fault! !
