Oh yes that's big for your age
I am 13 and mine is 5.5 inches erect and 3.5 inches flaccid, so really you should be proud
I do have alot more pubes than alot of people I've seen, so don't worry about that! It's fine, and besides, pubes don't really effect much of anything.
Also, please don't use that many smileys in a row, it's kinda annoying
