It was no secret that Kafka felt great embarassment and disgust in regards to the human body because to him it was a reminder of the passing of time and of its horrifying effects on man, it was a reminder of the clock ticking away which made him feel powerless. He most likely was overpowered by this awareness that engaging in the act was just a mere distraction from the passing of time. Franz Kafka had this longing for perfection, personal fulfillment and greatness so it was pretty obvious that, since he felt like he could never accomplish anything in his lifetime, he saw death as the definitive deadline to the point where he even asked that his literary production would be burned after his death.
