Yes you are normal.
It is big enough to do everything it is supposed to.
It is big enough for sex, but smaller than the average size.
Yes.As she said “It’s very big”
well the size of the average mans erect penis is 5.5- so for a boy of 13 years it is pretty big.
You are done. We all stop growing by 18 at the latest. So what? How big your penis is does not decide who we are or will become. Your penis is big enough to do everything it is supposed to do. Everyone is different and I have personally seen 2 inch up to 12. It simply does not matter. There is nothing to be done about it in any case. We all get what we get. No one said it was fair.
no, its called a lie
That's somewhat above-average, yes.
Be happy with what you have, but yes it is pretty big ;)
3/4ths of an inch
BIG ENOUGH believe me
