wow, your penis is as long as I am tall.

Very very small. Called micro penis

no one on here cares about your size but you

I think its pretty big!  Mine is only 4" erect.  I'm only 5'7 size 9 shoes but I'm over 21.  My penis was only 2.5" at 13!

Your penis size is fine, now finish doing your homework, and get ready for bed. 

It's big for a 13 year old kid and 5'6" is average for a 13 year old kid. I met a tall 13 year old kid at a grocery store and he was 6'5".

That is big for a 13 year-old.  Are you measuring your penis correctly on the top and not underneath?

that is really big

No it is not small!
