... But what worries me about this book is that I personally do not find myself in everything said John Gray women. So, inevitably, some men do not end up in everything he says about them ... Do not take the 1st degree, then, but this book is very interesting to understand the fundamental differences between female and male sexuality, and stop offending those differences. Instead, John Gray shows us that men and women look the same, but use another way to reach their goal. So this is a much romantic book that "erotic".
