whats conidered to be a big penis when erect? How 'small' is a small penis in cm?

Answer 1

Well there have been several different studies over the years and the results have varied a little, but the average penis size is between 12.9 cm and 16 cm. I'd say it's all in the eye of the beholder to determine what is considered small and large, as an average is just what most men have. Some women might think most men have really small penises, and some may think the average length is way too big.

Answer 2

Terms like big and small are a matter of opinion. What's big to me might be small to someone else and vice versa.
