Penis growth?

Until 21? None. Nearly all guys are done growing in length by 14 to 15 and reach final girth by 15 to 16. Sure a tiny percentage grow outside those parameters, but I have studied several different medical studies on male penis development and size and being final size by 15 in length and 16 in girth is very consistent. 6.7 inches as measured along the top of the shaft, bone pressed (ruler pushed in against the pubic bone) is big, dude. Only 12% of all men are even 6 inches, and less than 5% of all men are 7 inches or more. As a tall guy you should be big down there, and you are. Problem for many guys your age is you hear other guys claiming to be much larger than they actual are-- 88% of all guys are under 6 inches but probably 90% of teen boys will boast they are sporting 7 or even 8 inches. They lie, since unlikely anyone will challenge them on their claims.

Thank you for telling us about your penis.

The penis doesn't grow until age 21.

Boys typically reach their completed, adult penis size by age 15 or 16. You've likely already stopped.

Holy smokes, don't worry about your size. You're already bigger than average and you will more than likely grow.

Lucky gals (or guys) that date you. Woowee!

Yes

Average adult size is between 5 - 6 inches so you're already a little above average. Don't go by what you see in porn. Those guys are not average. That's kinda why they're in porn to begin with.
