Penis size young men
I am little confused. After reading all surveys I made conclusion that average NBPEL is 5,3 - 5,8 inches and BPEL 6 - 6.2 inches but few days ago I read the article that explain the decrease of the human penis with age. Does this mean that average NBPEL for 20 - 30 year old man is bigger than the stats from all these surveys. I ask this question because there are surveys declaring the mean age 50 . Does mean that there are a lot of people in these survey with penis not equal to the size they have had 20 years ago? Some researchers measure the penis size after pharmacological erection. Does this pharmacological erection is 100% hard?
Does somebody knows when the penis start to decrease , does this affect all men and how this affect the penis size data?
