Is My Small ?

Ok, i have an uncirsized 5inch erect/ 3 flacid and im 15 years old. Im realy pissed off, dissapointed and evrything...It's lke i wont ever have a girlfriend, i mean untill she sees my ..I dont have underarm hair, i got piubs though. This is like my biggest problem, always puts me down..The only thing that keeps me to life is that "it might grow an inch or two...". What about when i get married? My wife will probly cheat on me with a normal dude. This is kinda a "through it out of yourself" question..Yea so thats my story. Just tell me something, anything...thanks
