I purchased this textbook for a human sexuality 3500 class. I took the class online, thus the importance of my comprehension of the material within the text was crucial. I may have slightly enjoyed a textbook on occasion, but more often than not they are simply a means to a grade. This was not the case with "Our Sexuality", which I loved! Sources cited within the text have led me to more reading, I even purchased a few first editions of the works of Kinsey, Ellis, and Masters & Johnson that were referenced early on. I had a friend visiting from out of state and she read the entire textbook over her weeklong stay. I briefly questioned selling the book back, (I normally await, eagerly, at the chance of pawning off my pile of overpriced unused crap that they call textbooks.) But the need to purchase new overpriced crap for the coming semester led me to list the book on EBay, it sold for $50.
I saved almost $30 by purchasing the textbook through Amazaon instead of the bookstore. Amazon has certainly become my preference for purchasing textbooks.
