Hmm the whole thing seems pretty backwards to me, although it's logical and you're probably right. Thinking about it, I figure that in a sexual role play or BDSM or whatever you want to call it, they know, in their heads, that it's a game and that they are, in all truth, in charge..Whereas, if they truly convert to Islam and go through with all that, they're not.
Still, the idea that someone would willingly give up their freedom and their power is astonishing to me. And frightening.

Thank you for the recommendation, I'll look it up - sounds really interesting. And I agree, that's the purpose (or at least one of the purposes of art - to make people question things, to make them feel.
