According to a study reported in the journal Psychology of Men and Masculinity, the erect penis size of most men — 68 percent — is between 4.6 and 6 inches long. About 16 percent of men have an erect penis size longer than 6.1 inches, and of those only 2.5 percent are over 6.9 inches.
Considering this, is 5.5 inches a good size?
5.1 to 5.5 inches is the average penis size while erect. Most men are 1 inch from this average size, give or take. The preferred 6.3 inches is within the average range. Women’s orgasms involve much more than the size of a penis.
