My youngest son who is now 21, did not shot up so to speak until he was 15-16 years old, and it left him with stretch marks on his back, he is nearly 5ft8. Where my other son who is 25 is only 5ft4 or thereabouts. It all depends on who you take after, your mum or your dads side....
But most males do not stop growing until they are 21 where female grow earlier. You seem to be at a good height anyway, so why worry.....you can still get the girls....lol...
I had a friend who was 7ft, she hated it, her father and mother where both over 7ft and she was only 15, all the kids had to look up especially the girls, if they wanted to talk with her....she use to bend or stoop, so she didnt feel out of place. So it really isnt too much fun being tall, enjoy you for who you are....
