Hey man. I will give you a piece of advice: don't worry. It's all normal because not every body is the same. Some guys mature and develop faster than the others, and that's just the way it works. I was a late bloomer myself, didn't have armpit hair until I was 19, but I wasn't worried about it because I knew i had hit puberty. You just need to give it some time, for your body to mature, and in no time you will start to notice the change in your voice, as it will go deeper, and facial and pubic hair. It will all come in time. Being half indian doesn't affect it at all.
