Many people might think that it's almost impossible to get thrown out of a swingers resort for "inappropriate behaviour". The very practise of partner swapping itself is widely held to be inappropriate, after all.

However, such an eviction did take place recently, at a swingers resort in Queensland.

We are all familiar with the notion that men want more sex than women generally, and that marriage tends to kill the sex drive, particularly in women. Of course, men's frustration at not getting enough sex in marriage has long been used by humorists for comic effect.

Many people would argue that the situation is not that simple; that women are just as lusty as men, even in marriage. But according to Australian sex therapist Bettina Arndt, it seems the stereotypes are very accurate. She has done a lot of research on this topic, and included her often depressing findings in a new book.
