Hi Pablo seems that you are just a late starter, you could see a doctor and ask him about hormon treatment of some kind that will give you system a kick start, but if it gets you going it will still be a coulpe of years to see some real improvment in growth, you facial and pubic hair may get away but the rest willtake time.
Good Luck
Talk to a doctor. You might just be like my friend, who was 5'6" when a freshman in college and 6'2" when he graduated 4 years later. Some people's growth just comes later. But the doc should be able to check you out and make sure you're on track in all ways.
