As an instructor of Human Sexuality, I have used several textbooks over the years and I always find that (while adequate) there is always something missing from each of them. You know what that means ... buying and using more supplementary materials.
This is the first textbook I have ever seen that is simply PERFECT just the way it is. I will use it in every single one of my future classes. The students, faculty and staff agree. This is the one Human Sexuality book the whole world should read.
Bravo!
