A book was released a little while ago by a respected sociologist at LSE, considering the 'erotic capital' which women possess and the idea that sex work evens the score between the sexes.
There's a thought-provoking review from author Will Self here: http://www.guardian.co.uk/books/2011/aug/19/honey-money-catherine-hakim-review
(Mostly good, but I think his difficulty with the references to sex work are reactionary rather than reasoned.)
Just wondering if anyone's read it-- I've ordered myself a copy.
