I think that if there were no ropes or rope marks (they tell an ambiguous story), that this might be close to straight porn. Or perhaps not- there is the low point of view and fade to black which makes it interesting and/or different as well. I'm always worried when shooting that my images look too porntastic- because then I'll have to discard it completely. I not concerned about some closed minded viewers that may think all of my work looks like porn- they can fuck off because they're wrong (says me). If someone who tends to admire my work thought an image looked like porn, though, I'd be embarrassed.
