Not sure if this has anything to do with anything but here's a view from my end:

I love feminism because it provides the sharpest contrast to misogyny, which I find to be a very erotic BDSM play element.

The reason is simple- if taboo is exciting, and taboo is based on deviation from the norm, then what is more of a deviation? A hooker begging for a slap in the face? Or a Riot Grrrl doing the same?

Feminism lends itself to rituals of servitude simply because it casts the extremity of the sacrifice being made into sharp relief. I could use a "doormat" as my footstool for an hour but what is she really giving up, when she has no convictions or self-esteem anyway? I wouldn't even want to do that, it would be like taking advantage of an invalid.

Now, a feminist serving as my footstool- that's a noteworthy gesture of submission. As a feminist she has a full grasp of the implications of her act, but she does it anyway. That's hot, and it proves more in terms of devotion and trust than a hundred meek and mouse-like submissives happily performing the same act.
