It is inevitable that one compare this treatise on the scientific evaluation of the deepest human passion with the comprehensive works by Kinsey on the human male and human female published more than a decade ago. The detailed description of the primary and secondary sexual organs of each sex is documented by Masters and Johnson with physiological observations— quantitative in several functions— of various responses during intercourse, including the nipple response, contracture of the rectal sphincter, ventilatory rate, heart rate, blood pressure, dermal flush, and sensible perspiration.
The report comprises repetitive experience with a research population of 382 women and 312 men. One physiological observation frequently rumored, but never previously confirmed, concerns the sexual interest and sexual capacity of those eligible for Medicare. The oldest male in the study was 89 years of age. The factual presentation transcends any accusation that the work is pornographic to the unstimulated.
