Build Not Related to Penis Size
A man's weight, build and height bear no relation to the size of his penis in either the soft or erect state, nor is penis size related to his foot, hand or nose size. Art and the media, particularly men's magazine's and erotic books and movies, often portray male genitals in "larger than life" dimensions, giving men an unrealistic standard of comparison that can contribute to their concerns about their penis size.
Concerns about penis size are common among men of all ages. When a penis is soft it usually hangs loosely away from the body and averages about 3.5 to 4.5 inches in length and one inch in diameter, though some are smaller and some are larger. The same penis can vary in size even when soft. For instance, cold air, cold water, fear, anger or anxiety causes the penis, scrotum and testicles to be pulled closer to the body, thereby shortening it.
By the same token, a soft penis can actually lengthen in warm conditions and when a man is completely relaxed. Although the size of the non-erect penis differs widely from one male to another, this variation is less apparent in the erect state.
Masters, Johnson and Kolodny (1986) in their book "Sex and Human Loving" state that erection can be thought of as "the great equalizer" because men with a smaller non-erect penis usually have a larger percentage volume increase during erection than men who have a larger flaccid penis.
Penis — Bigger Not Necessarily Better
The great interest in penis size is related to several different things. First, it shows a concern for being "normal" — the same as everyone else, or certainly no worse. Second, it is related to a wish to be sexually adequate. Many people in our society believe that "bigger is better" and the myth that a big penis will provide more sexual satisfaction to a woman is widespread.
Actually, penile diameter has little physiological effect for the woman because the vagina can gradually adjust to fit a penis of any circumference (remember, it is designed, under the right conditions, to allow a baby to pass through the same opening).
The length of the penis, which determines the depth of vaginal penetration, is relatively unimportant, because it is the first one-third of the vagina that has the most nerve endings and is most responsive to physical stimulation. Penis size may, however, have positive or negative psychological significance to a woman. Some women prefer a large penis; others are put off by what they think is "too large" or "too small". Third, men may feel that a larger penis gives them an element of status and makes them more sexually attractive.
