My genitals are only 6 inches

Hi that is above normal for your age because that's around average size for an adult male.

Yeah, that's pretty well hung for your age, most guys have to wait longer to get that big of a penis. Congrats, you're hung big dicked for your age. Now show it off to everyone and enjoy it before the other guys your age begin to catch up in their penis growth and get as big as you lol.
