简单来说，地球上百分之七八十的人的尺寸在11-15cm之间。

具体的分布图，给大家个链接，摘自科学杂志的新闻，science与nature这两本杂志应该都听说过吧没听说过的应该没上过大学

“According to the team’s analysis, the average flaccid, pendulous penis is 9.16 cm (3.61 inches) in length; the average erect penis is 13.12 cm (5.16 inches) long. The corresponding girth measurements are 9.31 cm (3.66 inches) for a flaccid penis and 11.66 cm (4.59 inches) for an erect one.
A graph of the size distribution shows that outliers are rare. A 16-cm (6.3-inch) erect penis falls into the 95th percentile: Out of 100 men, only five would have a penis larger than 16 cm. Conversely, an erect penis measuring 10 cm (3.94 inches) falls into the 5th percentile: Only five out of 100 men would have a penis smaller than 10 cm.”
