When I was your age, I was about 5'11" or 6'0" and maybe 160. Now, (11 years later) I'm 6'1" and 250 (or more ... I haven't stepped on the scale for a while, and with good reason

). I was an early-bloomer, though. If you haven't spurted up yet, you still may.
Oh, and more importantly

, you'll get bigger "down there" for a few more years to come.
