s04e04 What's Sex Got to Do With It ?

Everyone is having sex except Miranda. She's on a sex strike because she's tired of going on bad dates so she substitutes sex with chocolate. She finally ends her strike and masturbates. Carrie is having mind blowing sex with Ray, the jazz club owner, in hopes of forming a relationship. Charlotte is having great sex with Trey but is angry with him for not asking him to move in with him. He later comes to see her and not only does he ask her to move in with her but he also asks her to re-marry him, she accepts. Samantha decides to give relationships a try because she really likes Maria. She tells Carrie, Charlotte and Miranda that she's in a lesbian relationship and they support her when she tells them that she wants to have sex when it feels right. It apparently feels right rather quickly because the following day she's telling them about how great sex with another woman is.
