2 The Psychobiology of Sexual Arousal and Behavior David L. Rowland Sexual arousal, as well as its end point, sexual behavior, involves a web of physiological, psychological, and, cultural factors. Yet like most other biologi- cally relevant behaviors, the personal experience of sexual arousal and response seldom reveals the complex mechanisms that underlie it. When a problem in- terferes with this mechanism, we are strongly motivated to analyze it, and only then are the intricacies uncovered.
