Given the subject being discussed, I decided to transcribe, with precision, the results of an interesting survey that it is possible read online. This poll is important because shows how, by varying age, changes the degree of coverage of the glans (with flaccid and uncircumcised penis). Overall there have been more than 2000 votes. Precise also that the participants were divided into various age groups; I, for greater simplicity, I divided the voters in these five fairly homogeneous groups: 10-13 years, 14-19 years, 20-30 years, 31-40 years and over 41 years. In the first case, we find those who have not completed puberty, in the central groups we have the boys and in the last I have placed men. All this will be clearly visible in the image, containing the results, attached. I want to add a small preview of the poll results and a note. Regarding the results, it is clear that, with increasing age, decreases the degree of coverage of the glans, this for various reasons: the end of puberty, shorter or more loose foreskin, a more frequent sexual activity etc. Finally, it is important to always remember that these data are the result of an online survey. By this I mean that the results still must be "interpreted". Specifically, they make us understand that, for example, is simply more likely to find, among older boys or men, people with a glans not entirely covered. However, it is also known that, except in exceptional cases, when puberty ends, the length of the foreskin then remains more or less stable over time.
