There is no correct thing to do regarding pubic hair. The hair is natural, so most folk just leave it alone. Many trim their pubic hair if it is very long or bushy, whilst a few shave it all off.
Shaving it all off can make you look undeveloped like a child, especially as a teen, so may get you some odd looks and comments from your mates.
Another problem with shaving is that the hair will grow back and the stubble can itch a lot. Furthermore, it is very easy to cut yourself, especially as your scrotum is wrinkly and quite thin.
My own personal preference is to leave my pubic hair alone in the winter but to trim it short in the summer. Only you can decide what is best for you though.
