Stephanie Sellars writes about erotic spanking for New York Press' Lust Life column:
There’s nothing like a good spanking after a hard day’s work. A hearty slap on the rear awakens the senses and gets the blood flowing. Maybe that’s why it’s sexually arousing—that sudden boost to the circulation reverberates in every direction, expanding evenly like ripples in a lake, flushing the genitals with heat. A pain in the butt becomes pleasure in the crotch because the nerves are so close. It’s an involuntary response.
She paints a pretty picture -- as, apparently, did the spank-er (as opposed to the spank-ee) she writes about:
Everybody else stopped what they were doing to watch. She handled that monstrous instrument of torture with such grace, as if she were painting a landscape on his derriere.
Completely regardless of my personal feelings about spanking as an erotic activity, I love how mainstream it's become. Spanking was once considered the domain of the seriously kinky (though I'm sure many secretly fantasized about it and even tried it out). Now it's out-and-proud, and the kind of activity that even those with otherwise very vanilla sex lives can engage in without feeling like they've crossed that invisible line to "kinky".
