Because if you demand respect while while simultaneously being choked during sex you're an empowered feminist, or something.
At Toronto's Globe and Mail, "I consider myself quite the feminist – I really think gender equality is very important, but sex with my new boyfriend has me questioning my feminist ways. We have been having sex for three weeks now and it gets physical. To my surprise, I have found I like to be dominated. He hits me during sex and chokes me, and I actually like it. I find myself asking for it. How can I be a feminist and still enjoy this?"
