At thirteen years old, physical development can vary greatly among individuals. A ten-inch penis would be considered well above average for an adult male, so it is unlikely for a thirteen-year-old to have reached that size. It is important to consult a healthcare provider if there are concerns about growth and development.
that depends on his motives

a thirteen year olda boner is about from 4 to 5 inches may be six it depends on your size if you way more it is smaller if you are say 90 to 120 your penis will be bigger and it depends on your puberty level tip: to make your penis look bigger shave the pubes and for arm pit just trim it cuz girls like it
