Is this the same for a black male? I am 3.8. Can you explain this to me?
The development of the human male is the same regardless of his skin color. I would like to add illustrations of different ethnicities at different stages, but it will likely take a while to find examples.
An answer of 3.8 means you are in the latter part of stage 3, the stage where boys grow the fastest. Since each stage lasts roughly two years, it means you are in the last six months of being in stage 3.
