Consult your doctor.
5 inches (which is about 13 centimeters) is the average size penis on humans.
Above Average.
A normal 24 year old would have a penis of between 5 and 7 inches long.
If you are 13, the normal length of your penis should be between 4 and 5 inches.
It should be two feet long!!!!
That is 100 % perfectly normal.
Above average, so don't worry!
yes that is around the average length.
It is normal
yes mine is
No, it is within normal size for your age.
well the size of the average mans erect penis is 5.5- so for a boy of 13 years it is pretty big.
