The most reliable way to do this is simply to wait until puberty has completed. The genitalia of both females and males changes during this time, and one of the changes in males is the enlargement of the penis. Puberty normally starts between the ages of 9-14 in males, and can last a number of years, normally finishing before or up to age 20. More information on puberty can be found on the BBC's interactive website.
You haven't stopped growing yet so it will get bigger. There's nothing you can do.
by ageing....
No. you're still growing and will eventually get bigger, maybe even MUCH bigger. You shouldn't be worried at this age. Your penis doesn't stop growing until youre 18-21, so you have plenty of time to grow and develop
No, it is within normal size for your age.
No. WikiAnswers does not show photos or diagrams.
its bigger im 14 & have a 5" when hard like 2 or 3 when not
There is nothing wrong with having an 8 inch penis, though large for your age just enjoy it.
yeah as long as it doesn't have a penis on it or anything :/
You can't. Be content with what you have.
unfortunately with out the use of hormones there is no way of enlarging a penis.
well.. its different in everyone.. personaly it happened to me when i was 13.. so you should start soon.
No need to worry as you are still a little boy of 13 years , there is a chance that it will grow as there is time for it . Yeah, your still young. But usually guys your age go from being 4 in to 6 in so, you are kind of small.. Its not like your 10 or anything your friggen 13 LAWL. But hopefully it will get bigger. Maybe you should try a penis pump?
