It's totally normal to read and like BDSM stories. You probably feel weird because BDSM is seen as taboo by society, it's seen as abnormal but it's really very normal and there's no shame in liking it. ^^ I read BDSM stories all the time because I'm really into that sort of stuff. A lot of people would probably enjoy reading these sorts of stories, but most just don't want to admit it.
This sort of stuff isn't weird at all, it's totally normal. :)
I don't think it's weird, just saying. I would love to read some *good* stories like that, but it seems all I can ever find is very awkward stories or ones that aren't very well written. But, no, it's not weird.
I read a 15-chaptered BDSM fanfiction last night, on this site called Archive of our Own, if you've ever heard of it. They weren't short chapters, either. I read BDSM fanfiction all the time, it isn't weird at all. At least, not to me. Some people aren't into that, which I can totally understand. It doesn't make you creepy or anything like that. A lot of people read about it, and that much, and then some, write about it, so.
I'm really awkward when it comes to that kind of stuff. :o I remember I started reading one story, I think it was for comment swap. And it starts normal and all of a sudden Like, I had no idea what most of that stuff even meant. And every chapter was like that too but with different people.
But, yeah. When a story is rated NC-17 and it's fan fiction, it's probably because it's pornographic.
