The Very Late Afternoon of a Faun (1984)

A bachelor named Faun with a Don Juan complex, seized with a hypochondriac's fear of the ineluctable approach of death, enters a race against time's passage. Faun's sexual love is imbued with the narcissistic vanity of a self-satisfied bacchant who even towards old age can't manage to forgo his lifelong pose as an irresistable seducer of women. He desperately searches for meaning in superficial, fleeting sex.
