Penis size
The average length of a grown man's penis is between 3 and 4 inches (7.5-10 cm) when flaccid and between 5 and 7 inches (13-18 cm) when erect. However, there may be great variations in size from one individual to the next. Contrary to some widely accepted myths, the size of the penis is not related to a man's body build, skin color, or sexual prowess. A very short man may have a larger penis than a tall one (and vice versa), a white man may have a larger penis than a black man (and vice versa), and a man with a small penis may have more orgasms than a man with a large penis (and vice versa). Furthermore, some penises which greatly differ in size when they are flaccid may be of identical size when they are erect.
