I think I remember seeing the book ‘The Joy of Sex’ in my parents bedroom. It may have been a bad dream or I could have subconsciously removed it from memory. Pop culture suggests that the ‘70s was a dirty decade. With the release of Deep Throat, the birth of Hustler magazine and just look at the guy on the cover from the first edition of this famous book that was released in ’72.

In ‘The New Joy of Sex,’ the suggestion of having sex on a moving motorcycle, which was included in the older editions, has been omitted. Perhaps this decision came after legal issues arose from people actually trying it. Not only would it be illegal in most states, it probably isn’t very safe either. It would however, be quite a challenge. It would also be one hell of a memorable ride!
