I was just going to let this thread die, but, since someone responded...
For me, I think there's a difference between a Tara Tainton type performance where she's role-playing as a dominating female but otherwise still engages in sexual behavior and/or nudity that would be considered exciting to a normal hetrosexual male. That is the kind of material I think you're classifying as tame role-playing and I'm okay with that.
What I'm calling out is the content where some chick is non-nude the whole video and engaging in humiliating talk. That's about as appealing to me as gay porn.
Everyone has their own taste in women, and so I may click on a thread and see giant fake tits and say that's not for me. But, at least I know me and the poster are both on the same wavelength and if someone were to find my browsing history, no big deal.
But, when I click on a thread and see it's targeted at some guy who gets his kicks off being submissive and humiliated and told to eat his own cum, that's not something I just say, "hmmm... nah, not in the mood today, maybe tomorrow" and it's not something I'd want someone to see on my browsing history. It's a totally different sexual preference that seems to belong in a different section.
But, there's not been a whole lot of response supporting my position, and I've been kind of surprised by that, so perhaps my tastes are more unique than I think.
