It is the more hormones that are being produced in the body at the time of puberty. These hormones cause physical changes, one major one being the growth of hair in new places on the body.
It varies quite a bit; some 13-year-old boys will have some chest hair, while some men don't start growing any until they're in their 30s. Men's body hair doesn't finish growing until somewhere in their 30s.
Different men get chest hair at different times. Many 13- or 16-year-olds will have some, and for a lot of men their chest hair grows in in their 20s, but most men's body hair doesn't finish growing in until they're in their 30s. You could be completely hairless and then suddenly start growing body hair in your 30s. Not all men develop chest hair, however, but most men have at least some.
Different women have different tastes; probably about half of women prefer some chest hair on men--and some of them even prefer LOTS of chest hair.
No but it dose put some hair on your taint!!
None; chest hair and body hair are determined by genetics and age and by nothing else. If the adult men in your family have chest hair, then you probably will get some too--though in many men chest hair doesn't grow in, or grow in fully, until their 30s.
Not necessarily, but a young man with hairy arms is more likely to develop chest hair at some point (usually by his early 30s).
Malnutrition is often what makes hair stop growing. Hair growth also decreases as a person ages and some hereditary disorders will cause hair to stop growing.
Some do. Some don't.
may be it takes a week or 10 days, but why do u do waxing, do you have more hair on chest, you can go for some hair removal solutions
Just because some girls have more hair then others but they don't alot but some girls do
Like most things to do with puberty it is very variable and indeed some men never do grow any hair on their scrotum. Next time you go to the beach or the swiming baths you might notice that while some men have a thick growth of hair on their chest, some have much less and others have none at all. Of course some men may have shaved their body hair (and some men also shave their pubic hair and scrotal hair) but many men just don't grow any chest hair at all. Every body is different and some guys have much more body hair than others. If you already have pubic hair, and hair by your anus, you might expect to see some hairs growing (even if they are tiny) on your scrotum, if you are going to grow them.
You can buy some hair growing solution if you wish...
