I am and 16, and you shouldn't worry about how you develope.
Well, my first idea would be the same as JB, just don't answer when your friends ask about that kind of thing. Not to insult you or your friends, but using bodily growth as a form of accomplishment is a little stupid. Its a natural thing, and shouldn't be looked at as a race. And for a person to think they are better than another because they have more pubes is just plain weird, and the person claiming this is just stupid, and needs to feel big. If their biggest accomplishement in life is growing a few hairs than the jokes on them, lol.
I have friends who are a little slower to develope, but it doesn't bother me at all. Anybody who is going to citicize you because of your progress in puberty isn't a good friend anyway.
And in my expirience, when puberty hits, it hits hard. I had (and still struggle with, a little bit) ance. My facial hair is out of control, and I shave daily (a real pain). Back, chest hair, my legs are a friggen forest... My point is you will get what you are asking for, in time. The stage I am at is ahead of my friends, so it does make me feel a little awkward. I guess I have the exact opposite problem, lol. EVERYBODY developes at different speeds. Don't worry about it. Don't let that define you.
Good luck, and if you have any other questions, this is the place to ask. You are incredibly brave to come forward with a problem like this, and that should be noticed.
Agian, good luck! And be proud of who you are!
