When your penis grows to be too big and causes the nerves in most of your lower body to go directly to your penis, therefore there are not enough nerve endings in your legs and feet causing the person to have extreme difficulty walking or performing simple tasks involving the legs or causing the legs and feet to be rendered completely useless in more severe cases.
