I'm 14 years old and very insecure about my penis size, will it get any bigger?

I'm 14 years old and have a 5.7 inch penis -- I'm not sure whether this is a good size or not, I am constantly insecure about it and, at times, think and end up upset about it. And so I really, really want to know: will it get bigger? when? and approximetely how big, a inch or two?
