Do nothing. It happens all by itself.
When you hit puberty.
Depends if he has started purberty
Congratulate him. Hope it doesn't grow larger in the fear that women may be afraid of him.
yes when u turn 14 it will grow lik 5inches
12 inches!!!!!!!!!!!!!!! 7-12 inches!!!
Depends but you are not done growing!
IT'S VERY VERY VERY RARE, if you are 12 your penis should be 3-5.
Yes its normal for a 12 year old. you are growing at different rates bodily so your testicles will grow later.
About right for a 12 year old, and very very large for a 6 month old. LOL no i mean i am 12 and 1/2 years old
Not necessarily. Those two things are unrelated and you will continue to grow through your early 20's.no!
No its actually big
for me my penis was 2 inches long when i was 12 and increased to 4inches the following year and now im 15 and my penis is 6.5inches
