Considering what fandoms are like I'd say you are the unique flower. I know you may feel alone or ordinary, but there's definitely nothing wring with what you like or don't like. A lot of people come to fandom to get what they can't get from the original material. If what you like is what is generally present in the original material dig deep inside yourself and see what it is you are looking for in fandom. And it's nothing beyond het and vanilla, then that's fine too.
