Observers for linear systems Book

This one was added to my collection while I was majoring in psychology at the University of Washington, and on the recommendation of my only girlfriend ever, Patty. Read the first time in 1976, while I was making a last gasp effort to convince myself that I was straight, the overall impression I got then from this book was that sex with women might be very complicated. Reading it now, after nearly 30 years of water under the bridge, the main message of the book seems to center around the individuality of sexuality, and how a mechanistic approach tends to diminish the pleasure for most. During this reading I thought often of the young women I've met in recent years, and wondered how things are different for them, compared to how it was for the young women of my generation… or my mother's.
