Here are a few good books about Sex and UNDERSTANDING about it honestly. They are not the only books but some. There are many. There are some that are good and some not so good that are available. I am only listing these as a way of having others who many not know about these to find out about them. Others can list what they have read that are very good also. SEXUAL BEHAVIOR IN THE HUMAN MALE and SEXUAL BEHAVIOR IN THE HUMAN FEMALE, by Dr. Alfred Kinsey and Associates; BIOLOGICAL EXUBERANCE, by Bruce Bagemihl (St. Martin's Press); FORBIDDEN FRIENDSHIPS, by Michael Rocke (Oxford University Press); THE CONSTRUCTION OF HOMOSEXUALITY by David Greenberg (University of Chicago Press); SCIENCE OF DESIRE, by Dean Hammer; SEXUAL BRAIN, by Simon Levey; THE INVENTION OF HETEROSEXUALITY by Jonathan Katz; these are just a few I have read that are very good and very well written and give the sources so you can check their findings... If you know of more, please list them here for others to see and read. The more a person knows about a subject in all its aspects the better off they are as Human Beings and that translates to others they know and care about as well. Take Care, John H.
