Hello, I am 13 yrs old. I was chatting with my friends and they said they had around 4.5 to 5 inch peni (I don't know the plural). I only have a 2 inch penis( when I'm hard) and I am a little overweight as well as worried. People tell me its just the rate of growth but I differ. Should I be worried?
No. You don't have to be worried. Your penis can grow into your early 20's.
Your friends are probably not telling you the truth. Average for a 13-14 year old is about 3-4". Most guys are just starting puberty and it CAN and DOES vary widely.
Don't compare yourself to others. We all develop at different rates/times.
One thing though, being overweight can make your penis appear smaller. A layer of fat around the abdomen/groin can "hide" part of your penis.
Hope it helps.
