Yes, average adult male size is 4.5 in
No, it's fairly normal.
I'm 15 and i have a 8 and 1/2 inch penis and the average penis for a 15 year old boy is 6.2 inches when erect and 4.1 inches around
Yes you are normal.
Between 15 and 16 µm
Not to sound rude but i highly doubt that u have an 18" penis
it is actually the average size.
It's big for an adult. Average adult is 6 to 7.

If you are 15 years old , and have a 3 inch penis and it is 7 inches when hard then it is quite normal.
