s02e06 The Cheating Curve

Where does the line between cheating and not cheating stands? The four glamorous women from Manhattan discuss the topic while going through their own experiences. Charlotte is having an opening at her gallery, where she walks in on her date making out with another woman. She is intrigued by the "powerful lesbians", a group of well-dressed, successful lesbians with good shoes. She accepts an invitation of dinner from one of them and has a great time on a men-free environment (the G-Spot, the newest, hottest girls club in the city), but soon faces restrictions due to her heterosexuality. Meanwhile, Samantha discovers that her hot personal instructor (that shaved her privates in the shape of a lightening) is giving lightening to other woman. Miranda has a tough time competing with porn when she discovers her date can only have sex while watching porn. And Carrie has trouble revealing to her friends that she is back together – officially – with Mr. Big.
