If you write something, don't hold any delusions that it's NOT a fetish piece if it is one, but there's nothing wrong with that either. It can be done tastefully.
What are the various choices though? It could be primarily for the purpose of fetishes. And that's fun since the possibilities with the rock are pretty much limitless. Or, it could be actual legit stories that are not heavily sexually driven and that can be interesting too. Or a mix between the two. As I said earlier, I can be done "tastefully". Or the third possibility is it could be an ideological soapbox, a vehicle to express some underhanded opinions. And if they were civilized about it, they could react in a civilized manner to a rebuttal, and it could become a sort of philosophical discussion. One could only hope.
But they have no business how you get your rocks off. If they don't want to read it because your sexuality offends them, they can leave and go watch a video from their hero Anita Sarkeesian instead. Instead of what they're doing now for me, which is seething in hatred, dogging my steps and rating down everything I write, even if it's just an actual legit story that isn't heavily sexually driven at all, because they didn't even bother to read it and don't care what its content is and they have decided I'm their mortal enemy and they want to censor me. Because they're empty inside and their parents spoiled them as children and they have no idea what it's like not to get their way. Oh look at that, my latest story is 4.6 out of 10 from 5 votes. Who wants to bet that's 3 1's and 2 10's and that the 3 1's didn't actually bother to read it, they saw who wrote it and rated it a 1. And that 2 of them are the same person.
Just write your stuff, and don't let the mofos stop you. It's none of their damn business what titillates you.
