I gave out a link to the sparknotes in my email, and will repost it here: http://www.sparknotes.com/philosophy/histofsex/summary.html
don't forget to use the links to the left on this page to go through the different sections of the book
also, here is a link to a umn page about HOS (History of Sexuality).
and another from UC Santa Barbara
This one might be the best place to start because it focuses only on the first 50 pages of the book, and then you can move on your own from there.
also, don't be afraid to just look things up online. I can't promise what you'll find, but that's part of the fun!
