The Big Bang is one of the best sex books that I have read. It covers just about every topic that can be thought of and goes into great detail and is very informative. The first part of the book is called "Sex for Beginners" and it starts off with an introduction to masturbation. It starts off with reasons why to masturbate, tips for chicks, tips for guys, and ideas for different things to try to spice up your masturbation routine. The second part of the first chapter is about foreplay. It's not a very long section but the information is pretty detailed. The next two sections cover manual and oral stimulation. The book covers in detail different techniques for both partners. Finally is the section about intercourse and anal sex. The biggest information in the intercourse section is about positions. The anal sex section is very useful for beginners. This section covers anatomy, cleaning, the importance of using lubricants,ways to warm up and work your way up to anal sex, and positions.

The next chapter of the book is titled "Sex for Advanced Swimmers". The first section is about the g-spot and female ejaculation. This section cover anatomy, where to find the g-spot, and what female ejaculation is. The next section is about fisting. I'm not too interested in this section but it covers the basics of anal and vaginal fisting. The next section is one of my favorites, its about sex toys. It covers vibrators, dildos, butt plugs, cock rings, ect. There is a nice diagram that shows popular toys and lists the size, pros and cons of each, a description, and a price estimate. The next section is about BDSM, and it has a lot of information. This section covers the most common BDSM topics the average couple might be interested in. I think this section is great for people who want more information about BDSM and is very informative.

Part Three of the Big Bang is probably the most important and most informative part of the book. It is called "Sex for Winners" and covers sexually transmitted diseases. This section covers a very wide range of diseases along with symptoms, how its spread, the treatment, and how to prevent the spread of the disease. The next section covers condoms, which includes male and female condoms, and dental dams. This section covers the materials condoms are made from and a description of different brands. The next section covers birth control. The birth control section covers how each one works, the average of each method, the pros and cons, and the price of each method. The next two sections covers infections and ailments that could affect both males and females. The section after that talks about kegels. One of the final sections covers the importance of lubes. It explains the different types and compares brands. The very last section is about the male and female anatomy.

If anything, buy this book for the Part Three, "Sex for Winners". The information is so important and useful and stuff every sexually active person should know. I would highly recommend this part of the book for parents to discuss with their teenaged children.
