My penis is 5 inches long and it's not that big around. When well it grow?
Technically it has been growing. You are much bigger now than when you were a child. I assume that the length you gave is when you are erect. Growth in width comes during stage 4
of development. I would assume you are currently somewhere in stage 3
at the moment and are experiencing your growth spurt. It is during stage 3
that you gain the most length in your erect penis.
