It's really difficult to say how hairy you will be but maybe if you look at the male members of your family (dad or uncles) that might give you some idea of what to expect.
Hair is often a genetic thing, so you will find that men who go bald at an early age will probably have a father with a shiny head too!Obviously you are growing and your body is changing, you seem to be enjoying the hair so that's good, some people do think it is manly, it's personal preference.
If you decide you don't like it, eventually it won't be a problem, you can always shave or wax.
The plus side is that if you ever want to grow a full beard, it should be easy to do... less hairy men have a problem with this, so you may be the envy of all your friends.
Basically, 'time will tell' how hairy you become - but if it's like the guy in this photo you probably won't need a sweater in winter!
