I am an uncircumcised 15-year-old. Does being uncircumcised stunt the growth of the penis?

It's only 5 1/2 inches long when erect.

Don't be ridiculous! An uncircumcised penis is a natural one – all males' penises are uncircumcised when they are born. How could this possibly stunt your growth? Furthermore, you have no reason to be concerned about your size. A lot of guys reading this right now would happily trade their penis for yours. Please, don't obsess so much about the size of your sex organs. That goes for everyone out there.
