Not read Kathy Lette before, but thought the book was funny. Lots of sexy delicious one-liners, lots of them with an element of truth to them!
The book certainly takes the mickey out of married sex, clearly favouring the much more satisying subject of toyboy sex! Also loved the section called "Taking the Phallic Cure" under Infidelity on page 137. This section should make men wince! I wouldn't say that it encourages mid life women to stray, but it comes pretty close, whether their husbands have strayed or not!
