The relationship between anal sex and women has been seen as a bit taboo for quite a while. We decide to lift the lid on the issue and present you with "A women's guide to anal sex". Why do we do it? What's so good about it? What must we know before trying it? We also hear from a couple of women who can't get enough of it. To help us through the motions, we're joined by sexologist Cyndi Darnell.
