about dick size...

So I am in the former half of high school, and my dick is 5" erect. Is this average? By the time my penis has stopped growing, will it be average, above, or below? I'm not thinking of getting into any sex stuff, I just (obviously, like all guys) want to have a big dick. Obviously, all methods of increasing dick size are BS, everyone knows that. Just wondering :)A mildly insecure homosexual (relatable, am I right?)
