Guys grow in height starting at birth. But if you are talking about penis size, they start growing in the second stage of puberty, which is around 11-11.5 years old on average.
Not much, usually men are done growing by this age.
Around 14-17 to start growing. At the age 16-17 it will start growing faster and longer.
13 or 14.
At the age of 13 to 15

I'm 17, almost 18 and still dont have much facial/armpit hair. Dont worry about it- it will come when it comes. It might be a bit embaressing around the guys in the locker room but just be cool about it and tell them to screw off. Plus the girls might like it
Yes definatley and so does coffee but you have to start at a young enough age or it does not do anything.
Dude that's so totally awsome!
It differs greatly from person to person, a friend started when he was 14, i started when i was about 17.
