'In the arts generally and in literature in particular, depictions of sex are never a mere representation of life-they are more like a substitute for it, an alternative to it. They often express desires which cannot find fulfilment in reality, and thus are entrusted to the imagination by which, for all their 'baser' nature, they are turned, or sublimated, into something more acceptable to society, something that can appear on a canvas or a sheet of paper and relieve the artist's, as well as the viewer's frustration.'
