It sounds like you are just starting puberty and for your age that is normal.
All the things you are concerned about will change as you go through puberty you will grow more pubic hair, your penis will grow and your voice will change.
There is absolutely nothing wrong with you you are developing just as you should be for your age.
Everyone grows and develops at different rates and times and things are just starting to change for you.
There is nothing to worry about you just need more time to grow and develop.
