will my penis grow any bigger if im 14 and have a 6.5 inch dick?

Answer 1

A male will grow until he is 21 years old. As for the penis, the size is determined by genetics. Medicine will tell you that you need to wait until 2 years after you stop growing to know what size your penis will be as an adult. So, you probably won't know that information until you are 23.
