So how does one write sex scenes in a book without being prurient? There's a line that I prefer not to cross and I think it is a matter of taste. Some people write great sex scenes - Henry Miller's were gruelling, tinged with cruelty but totally engrossing. Others do not (Scott Turow for instance who reaches into the cornball bag for his descriptions.) It is the same with film. Taste and subtlety play a great role here. Having said this, the photo above is something that has absolutely no subtlety about it!
Ahhhh, the sounds, sights of the great outdoors suddenly take on a whole new meaning!
