I am 15 and need answers about puberty I think something is wrong...?

Im 19, not a big guy but by the time I was 15 I was well pubecessed. You,re just a late bloomer. Not every guy has leg hair, I for one have a lot and did by your age, but I have yet to have a full beard (close, it comes in thicker) and as for chest hair, I started getting the stomach hair at about 16, but just now getting the chest coming on. Some people pubecess at 12, and are done growing, others go into high school small and baby faced, and leave full beards and tall. I for one bloomed earlier then you did, but never had a major growth spurt, and im still in a sense changing. You,ll lose the baby fat, once you grow and fill out.
