That's what she said - literally actually - also what she did (or does) in the movie! So no pun intended - something I said and like to say. This has a lot of nudity and our main female character for some reason thinks that sleeping with someone ... well only can happen with someone she doesn't fancy ... because otherwise they would destroy that love.
Well I reckon you can make up issues to keep us on our toes (or any other naked body part of course). All kidding aside though, it is a character flaw if you want to call it that. And she does like to have fun - though only with someone she chooses too. That person has to get the signs and/or "convince" her a little too ... whatever you may think of all that ... I reckon it is enough stuff/story to fill in the blanks/holes ... of the running time and in between the love making scenes! Get your mind out of the gutter ... well a little bit at least!
