We've let our 13 1/2 yo daughter watch these films (including The Renunion) and she's suddenly taken to wanting a bath every night instead of a shower!
Anyone who has watched the film will know what I am talking about.
whilst I appreciate that they are a 15, she is not backwards in coming forwards about sex talk (after lessons in school and finding one of our porn films - although not watching it I hasten to add!) And we are very honest and open when she asks questions and wants to know stuff - we want her to come to us before playground tittle tattle
