Hard to find info...: Hard to find good, consistent info on penis sizes, but several doctors on HealthTap have offered opinions. At 15, it depends on the stage of puberty he is in. After puberty, it looks like the average erect one is 5-6 inches, so one might worry if less than 4 inches, and he can talk with his pediatrician. When non-erect, perhaps under 2 inches would be small. In the end, function will trump size.
