I'm currently working on a story that will be several chapters long. The first chapter has both f/f and m/f scenes, as will subsequent chapters. Later chapters also fit into interracial and incest categories (I think - do adoptive siblings who only really form a relationship as adults actually count as incest?). I've considered just posting as a novella, but I don't know that it would reach as many readers that way. Should I just post across categories? If so, how do I decide which category, when more than one us applicable?
