The penile length is correlated with your height and your ethnicity. Penile length for an average American is 5 inches so you are a little short. However, if you are an Asian American, you are not that short though. Please notice that the penile length is not correlated well with sexual satisfaction.

Lot of errors are made in measuring the length of the penis. So your measurement might be off. Penis stops growing after puberty. It is never too late for anything. If you have good erections then chances are you are normal. If still worried see a Urologist. I think you will be OK
