So after that horrible Roller Coaster thread, Feministing seems to be full of reasonable, positive discussions of kink and BDSM. Considering the way that every other discussion over there has gone, I'm impressed.
I'm a mathematics major in my mid-twenties. I'm also a (usually) submissive, queer, Jewish feminist woman (sort of). Mostly, this is just a way for me to get out all the ideas I don't have a chance to discuss in real life.
