It all depends, I'm 12 and I have put hair, leg hair, chest hair, etc. It all depends so don't worry about it, it's actually a lot more ackward when changing in gym and you have it.
It is not about how old you need to be but how far you have grown into Puberty. Puberty is the stage when armpit hair and pubic hair begins. Each child is different so age has little bearing on it, although puberty can begin around 10 years old for girls and 12 years old for boys so not long after.
Well to answer your question, "Is a 13 yr old boy meant to have armpit hair", my answer to you is yes! Right now I'm 15 and I have Armpit hair, Pubic hair, and Leg hair, A LOT of leg hair. I started getting Armpit hair when I was 12 so it's normal, you just are developing faster. Well I am 15 1/2, and i have barley any armpit hair, but i have pubric hair, and leg hair only on my lower limbs. I dont know why but this is how its always been, and it kinda sucks, because people who look like they are in the 6th grade have more armpit hair then me? Anybody telll me why please
Very little if any. It will probably not show up until 14 or so. It will vary though. Myself, i have quite a bit of armpit hair and i am only twelve.
Some do, and some don't. It's a matter of personal choice.
Armpit hair begins to show once puberty has begun.
The average age is around 12 years old. Sometimes it comes sooner, other times later. Usually around the age females hit puberty.
Don't worry, you will develop mature charactaristics, just the same as your friends. Some bodies mature at different rates, but by mid-teens they are mostly at about the same level.
Niall was 12 years old when he started dyeing his hair
he was about 12 years old
Pubic hair can start growing from the age of 10, and having hair at the age of 12 is totally normal.
A male penis will grow the most between the ages of 12 and 18 it will stop at about 20.
Normally probably not, some boys once they reach their stage of growth usually begin growing hair then, but sometimes a boy doesn't grow armpit hair until older age. I am not sure if you got it from your dad(genes/heredity) or not, but usually boys shouldn't have armpit hair in such an early year.
