Not actual bad sex, but the UK Literary Review’s annual Bad Sex Awards.
I’m a bit late on this — the results were out in December 2011, but I’ve just stumbled across it as I was googling to see if the latest novel by the amazing, incomparable Haruki Murakami is available in paperback. Yes, it is. Yay! And it’s a bad sex finalist. Not so yay, but having read a few of them, I have to say it’s a good pick.
