Describe EPOR. What are male and female sexual patterns?
EPOR was formulated by Master and Johnson in the 1960's. They independently observed 100 couples having sex. From this, they got a perception of human copulation responses.
E: excitement. This begins with arousal, tumensis (blood engorgement of erectile tissue). Both sympathies and parasympathetic activities are turned on:
Sympathetic: nipple, penis erection
