I highly recommend the new book "Hindsight" by Howie Gordon.  Gordon was the pornstar "Richard Pacheco" in the 70s/early 80s during the golden age of porn and fucked all the goddesses of that era, Kay Parker, Veronica Hart, Seka, etc.

The book is sexy and really funny in that 1960s/Lenny Bruce way.  I haven't read any of the other porn memoirs out there, but this one is great.
