Her latest book, What Men Want – in bed is also on sale in bookshops and online as an ebook. What Men Want – in bed is all about why sex matters so much to men. Over 150 men kept diaries for her, talking about what it is like to live with their strong sex drives. Their painfully honest, confronting, often hilarious stories explain their quest for sexual adventure, their secret delights, the thrill of giving pleasure, why some men turn to pornography and men's delight in the Viagra revolution. With every second man over fifty dealing with erection problems, Bettina offers advice on the wondrous new treatments giving men a new lease of sexual life. Read Introduction
