Giorni (2001)

Bank manager Claudio is 35 and gay, and he's been HIV-positive for a decade. He's managing the illness, but his strict regimen of medicine has turned him almost robotic. His relationship with partner Dario has also grown stale. When Claudio reunites with the mysterious Andrea, an old flame, the dullness of routine is suddenly broken. But soon, Andrea's romantic view of life tempts Claudio to engage in dangerous unprotected sex again.
