The Bug Killer (1971)

A coming-of-age story: the travails of Milan, a 15 year old who has difficulty dealing with being in the work-force. His father has gotten him a job killing bugs at the bakery he works in. He is unsuccessful in this, and continues to be unable to keep work. His father, in his concern for him, pays some whores to deflower the lad. Alas, even this does not go well. Clearly, the boy doesn't perform well on demand. The only person who can properly initiate the lad into manhood turns out to be his aunt, whose patience and humor triumph.
