Iconic sex book re-released with updates

But the new edition has been brought fully up to date 8212; for the first time by a female author, who, while praising the original author Dr Alex Comfort, says there was much that needed changing.

8220;Back in 8217;72 they didn8217;t know about hormones, about pheromones, they didn8217;t know about certain body parts and their importance, which we now know,8221; said author and relationship psychologist Susan Quilliam.

8220;A lot of research has been done. But also the whole attitude to sex has changed,8221; she said.

The new book is aimed at the couple, rather than just the men, and includes many new entries including advice on Internet and phone sex, sex shops and intercourse during pregnancy.

Quilliam noted that some tips from the original had to be removed, because they were illegal.

8220;One of them was having sex on horseback, the other was having sex on a moving motorcycle, although I do include guidelines on how to have sex on a stationary motorcycle,8221; she said.

The publishers of the new 288-page edition, Mitchell Beazley, said it would 8220;reflect the current attitude to sex and help bring the joy back into sexual relationships.8221;
