i sell dr. christopher's childhood disease book, that is an excellent read in the first 14 pages on sex an healthy marriage, but no man will like what he wrote.
what i call the sitz bath book is the superior book. i do have it scanned and prepped to use on the school one day, but it is a giant of a book, but the best book ever written on the woman and proper sex to avoid the inherieted diseases, etc...
that book is about 150 years old and written by one of the smartest mds the world has probably ever known..he understood the human body and the female.
