Don Jon (2013)

New Jersey bartender Jon Martello (Joseph Gordon-Levitt) knows what's important: his friends, his family, his car, his church, his sexual conquests -- and porn. In fact, Jon is a porn addict and has never had a genuine relationship with a woman. However, when he meets Barbara (Scarlett Johansson) he has to change his operating methods, because Barbara won't be bedded easily. For the first time in his life, Jon begins a real courtship, but his obsession with erotica threatens to ruin everything.
