What is the chance that a man at the same time likes hairy, dirty women, boys, sniffing panties, aged women, incest, and the like at the same time?
You think that you are expanding the audience, but in reality you are scaring away.
Maybe I'm wrong. I judge more on fan fiction, which I write in co-authorship, .... There also is not a single normal work that includes many fandoms. More does not mean better.
ps Besides. Fetishism is a rather rare occurrence in itself. If you understand it as a psychological, not a life term. It is rare when you can find a person who loves to smell pants ... strangers. Just shorts without reference to the person, age, or gender.
pps Although it is easier to write like that.
