Disingenuousness is not the right word, I think. Because I totally get the desire for story for the sake of story, not just as sexual release!!

I think I need to flesh out that whole idea more, because it's... I don't think it's weird that the bulk of people want some sex in their fic. Nor do I think it's weird to grow so weary of the sex for the sake of it that the real longing is for story.
