I almost wonder if she's not feeling you out to see what you know about the scene? But who knows. It's still not acceptable to be openly gay in many places and so many people have stereotypes such as "gays people are into kinky things", she might assume they go hand and hand and is looking for input or support. Maybe next time she brings up a little kink you could say "I know this really great site....." She'll have an in without you being completely blatant about it and you can see where it goes from there. Good luck.
