The gay chapter gives some examples of slash fiction, a genre that finds TV series characters reimagined as hypersexual homosexuals. I first became aware of this phenomenon at a Star Trek convention where illustrated stories revealed Kirk and Spock melding more than minds. Of course, the humorists pick the shows from which a reader would least like to see characters having sex: Alf, The Golden Girls, and Knight Rider. You'll never think of KITT the same way again.
The book offers amusing factoids sprinkled throughout, although "fact" isn't the f-word that they use. There are also helpful hints that inform what household items can be used as dildos. Dil-dos are bowling pins and cell phones on vibrate while dil-don'ts are light bulbs and cacti. While the "don'ts" seem obvious, I am sure one medical professional probably has a cringe-inducing anecdote to the contrary about one curious individual.
The Sexy Book of Sexy Sex should be called The Funny Book of Sexy Sex except for the part about impotence because there's nothing funny about that even if it does happen to everyone...or so I hear. Like sex, the book is enjoyable read alone or in groups, although if you can get a group to have sex, you might as well wait and read it alone.
