What's the average size of an adult human penis? Does the average vary among people from different continents or ethnic groups?
I have a question. What's the average size of an adult human penis? Does the average vary among people from different continents or ethnic groups?
On average, an adult human penis is around 5.16 inches in length and 4.59 inches in circumference when erect. However, it's important to note that there is a large range of normal sizes and some people may be smaller or larger than the average. In terms of variations among different populations, some studies have suggested that there are slight differences in average penis size among different ethnic groups or geographic regions, but the evidence is mixed and more research is needed to confirm these findings.
