Then there's erotica. In erotic writing, Sex is always at the wheel. If Bourgeois Morality manages to climb on board, Sex may press the ejector seat button. She may pretend to listen to his instructions while doing the opposite, or she might just tie him up, gag him and tickle him with feathers for the rest of the ride. She doesn't mind the company of Love, and usually welcomes it when it's there, but she's not too fussed when Love's not around, either.
Sex is a bad girl.
And so far as erotica is concerned, bad can be very good indeed. When I say Sex is bad, I don't mean bad sex. I mean bad sex. Not evil sex, though I acknowledge that there is a fine line that runs between those. I am fascinated by such stories as 'The Hungarian Adventurer' by Anais Nin, in which acts that would be absolutely reprehensible in real life, not to mention fully criminal, are almost unbearably erotic on the page.
