The topic of sex is often considered either from a biological or cultural point of view. Here is an attempt to combine both approaches and write a guide to human sexuality, telling how on top of powerful natural instincts are layered various psychological nuances, cultural codes and taboos. In their quest to answer the question of why the same basic natural mechanisms produce the most bizarre expressions of sexual activity, the authors examine topics ranging from the neurobiology of libido and the G-spot controversy to the reasons why middle-aged housewives are interested in gay porn. If you want to find out how your sexuality works, then thanks to this book you will get many answers, learn to ask the right questions and certainly begin to better understand both other people and yourself.
