Gabrielle Anwar's openness about her experiences was one of the best assets of the documentary. It's rare for a woman to reveal so much personal information into their thoughts with anyone other than their intimate partner. This insight helps women and men to understand and/or relate to their own relationships.
There was an almost too eclectic array of experts involved but I think they succeeded at least in not letting them contradict or distract from the lessons learned from them. It's a bit surprising to me that people don't understand that for women, the sexual experience is primarily something that occurs inside their own minds/hearts and that they have ultimate control of it.
