boys get in their older ages like 13to 14
no but they seam to mature faster than boys
Yes. Both genders start to develop underarm hair and pubic hair during puberty.
usually from ages 11 to 16 in boys and ages 10 to 14 in girls
Like most things to do with puberty it varies from boy to boy. There are several different processes which happen during puberty and they don't always happen in the same order. Some boys grow armpit hair before they grow pubic hair and with others it is the opposite way around. Boys also start puberty at different ages, any ages from 9 years of age right up until the late teens is considered to be the normal range. On average though most boys start puberty around 12 or 13. If you do already have some pubic hair then you'll probably start getting armpit hair fairly soon.
No.
you have to hit puberty
Humans grow armpit hair as a natural way to regulate body temperature and to release pheromones, which are chemicals that can attract potential mates.
Thy will start to grow and they will get darker. They will also start to grow hair
Yes you can make your hair in ypour armpits to grow, you must shave it then it will grow back.
This must be irritating to hear again, but it all depends. Usually males start pubic growth around 11-14, with exceptions. Facial hair usually grows around 13-16, and armpit hair at around 14 to as late as 17 or 18. Its all in your genes, so there isn't anything you can do about making it grow faster or slower.
