The rom-com game is always on the lookout for fresh sources of conflict, and sex addiction seems as good as any. In Thanks For Sharing, Mark Ruffalo plays a sex addict who starts dating a skeptical Gwyneth Paltrow. Ruffalo also is the mentor to young addict Josh Gad, who in turn is trying to help Pink. The film hits theaters on September 20. It's just like When Harry Met Sally, if Harry seemingly had sex with anything that moves — wait! Maybe, we should look at the movie differently.
