Penile erections: shape, angle, and length.
A U.S. Census-matched sample of 1,484 men between 20 and 69 years old from archived data of the Kinsey Institute and current questionnaire plus documentary photo data from a new sample of 81 men between 21 and 67 years old were analyzed to generate a description of penile erections that might act as a useful information base for therapists and others. Estimates derived from Kinsey data on erections were found to provide a credible foundation of fact, with the current questionnaire and photo analysis implying the need for moderate increases in the Kinsey figures in three areas: (a) more n-curved (downward curved) erections, about 15% of the total; (b) more erection angles in the lower ranges, with at least one fourth below horizontal; and (c) a greater proportion of shorter erections, with lengths in the 4.5-5.75 in. range, representing about 40% of the total.
