Not to sound rude but i highly doubt that u have an 18" penis
If a human has an 18 Inch long penis, then I have got to see it, and if you are 15 and that big, I'll get locked up just to ride it
No, you are completely normal. Average size of an erect penis on an adult male is 4-6", so you are right in the big middle of normal.
It all depends on your physical maturity and puberty. However if your 15 with a 7-inch penis you should feel awfully proud!
yes it is
No i think that's big but because im 13 turning 14 next year and i have a 12 inch penis when i not not hard but when i am immediately 13 in a half inches so your penis is not small.us
no man ull have that by the time ur 17-18
i guess Because Im 14 And I Have A 8 and a half inch Penis When Hard
yeah you should cause your 15, and your a male so you should keep developing till at least 18-19
Yes, it is normal for them as everyone is different at that age. Puberty will just be starting for some so the penis will not have developed as much as someone that started a year earlier. By the time they are 18 to 20 years old they will have caught up.
an 18 wheeler
Any size is normal =D.
