It wasn't hard and ended up being a quick, breezy affair. (That's what she said ! Ha !)
My rating might be a hit harsh given that I read the Emperor of All Maladies before this. If Watsa had the inclination or the talent, he could have made this into a masterpiece. Sex is probably one of the easiest and most universal things to talk about. Literature, Pop culture, movies, Juvenile jokes, double double-entendres, Feminism, history of sexuality.. It's all endlessly interesting; But let's focus on what the book has managed to accomplish.
The book is a much needed one particularly in conservative societies like India where there is no sex education and people's knowledge is based on what they have learnt from the internet, friends and in rare cases family. The book establishes the basics about sex, sexuality, safe sexual practices and tries to answer frequently asked questions. About half of the book focuses on questions previously sent in by readers. It's hard to maintain your interest after a while, as only a small section of the book and the questions would be relevant to you based on which phase of life you are in. (I don't want to know about slowing libido in the 5os and 60s. ) But what this book does is to try and establish the right attitude towards sex and sexuality. Looking at all the questions and topics addressed, you would feel that your issues, whatever they are, are for the most part normal. This is key, in a society where sex and sexuality are topics which are avoided and any strange behaviour is considered abnormal. Overall, it's a, dare I say, necessary read given the topics it touches on.
