This is a study on the sexual and a few other aspects of marriage based on a survey of one hundred couples. It is like the Kinsey Report in some ways but unlike it in others. The numbers are much smaller than those on which Kinsey reports. The investigation was based on cards of questions, each subject being examined separately in the private consulting room of the author. Questions were not asked orally, but were presented on the typed cards, of which forty-seven were used for each woman and forty-three for each man. The cards were passed to each subject and the answers were recorded together with notes on significant behavior reactions on the part of the subjects. The results are presented in tabular and narrative form. The author is guarded in his interpretation and conclusions.
