Normal size for 14 year old?

Well, I'm 14 and I have a 7 inch dick. Witch I'm pretty sure is not normal because I out done my 19 and 20 year old friends, but I guess the normal size would be about 4 inch for a 14 year old and your doing good I guess if your 5 inch. Because I found out that the normal mans dick is about 5.7
