The sex scenes are good not bad, I was wondering how Billi's body remains amazing after having 2 babies, out of reality. I haven't finished watching season 1 but as a man I found her very immature and stupid. If you are not satisfied in your marriage you need to talk to your husband and let him know what you want. If she wants to have the life she had when she was single then divorce Cooper and go back to Brad I bet they wont last more than 1 week before the first fight, it is a pattern that woman have, some of them like to be humiliated and they wanted the bad guy at all cost.
She should have never got married in first place stay single until you die alone and realize that man only wanted her for her body. Sad to be honest I have been married with my wife more than 10 years and sex is great after having one kids less may be less but amazing, he have talked about it we write letter each other and we grow as a couple, I love my wife with all my heart and I respect her a lot. Billi should ended alone Cooper does not deserve her.
