You are quite right Alex. I learned quickly in the world of publishing you have to keep your audience in mind when you submit a piece.
For the most part, the audience that frequents the library expect explicit sex, hot and degrading humiliation, a dilemma for the protagonist, etc., all within the framework of a story. And if the story is really good, you can get a bad rating for not continuing with it even if you think it is a finished piece. If you see those words, 'too short' then consider it a compliment.
I also concur with the comments of the other posters.
