I have a sense that I could guess at some of the responses I might get to this question on this particular forum. It was stimulated by a 2-star review of my book on Amazon, 'Stepping into Gina's World'. The book sees a letting agent, Georgina, who fantasises about being a prostitute for a sexual buzz, being sent a pair of thigh-high boots. Wearing them shifts her into an alter ego, i.e. Gina, who is a prostitute in the same town and indeed might be a version of her who had had some alternate turns in the road. Georgina fluctuates between trying to shake off this alter ego and indulging in it, until in the end the choice is made for her and she ends up fully becoming Gina.
Now, the review condemned the book as not being erotic because Georgina becoming Gina for good, given prostitutes' lives, is not a happy ending. I just wondered what people's views here might be on that as it is the first time that I have had one of my erotic books slated for not being erotic! That is despite the numerous sex scenes of different kinds in it. Does a story need a 'happy' ending to be erotica? If not, how do I alert readers like this reviewer that this is a different kind of book to what might turn them on?
