Just to say that I write my stories for "me" in the first instance. They are my fantasies - but I do enjoy knowing that I've piqued someones interest, especially if they find something I've written arousing.
If all you are interested in is writing a story for yourself what's the point of putting it on a website? Personally my favourite stories are the ones that arouse me - doesn't everyone seek out those things that will give them a "buzz" - thats one of the reasons we have story codes.
