I don't have HBO, so can you tell me, is at least one of these couples the normal HD man with LD woman, and if so, what are they doing to FIX the problem, and more importantly, is her desire level REALLY changing.
Cemar, Besides the couple I mentioned, there's a couple who is having fertility problems, and an unmarried couple using sex to fix their relationship problems, only to backfire ( apparently the woman uses sex compulsively to fill a void).
