I am a bear. As for your arms, legs, chest, buttocks, and back that all comes in time. I personnally was a bear by the time I was 15, but I have a few friends that are almost completely hairless in all the areas forementioned. Connor is totally correct.
Hair is a genetic thing, many guys have very little and some have a whole bunch.
Development takes time, so you may get more hair in those other places in time. If not, no big deal because most women don't care for really hairy guys.
