The average penis size for prepubescent boys, including 10-year-olds, is typically not measured in terms of "boner" length, as most boys at this age have not yet entered puberty. Prepubescent boys generally have a penis size of around 3 to 4 inches when flaccid. It's important to note that individual development can vary widely, and concerns about size or development should be discussed with a healthcare professional.
