It depends on what state of puberty the 13 year old is in. Some 13 year olds are more developed than others. If one is slightly behind on development, a 3 inch penis would probably not be small and it will get much larger in a few years.
Not at all. The average adult penis size is 4'' flaccid and 6'' erect. It is not worth worrying about penis sizes at all. Not only that, a penis does not stop growing until you reach around 20-years-old, and after Puberty has ended.
yeah
erect: Hell Yeah
non-erect: Hell no
3 1/2 inches in erect length is not big for a 13 year old, but it is very normal and can be very satisfying.
no mines 6 inches and im 15
If it is erect than yes because mine is 5.3 inches when erect
If you were an adult, you would be average. But, since you are a teen you will still grow, so, yes, you are big.
i guess Because Im 14 And I Have A 8 and a half inch Penis When Hard
That is about an inch over the wold-wide average.
No its actually big
ummm. just a little over, but no big deal!
Yes. You should be happy :)
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
That's the average size for adults!
no
3/4ths of an inch
It might grow another inch or so. but i wouldn't worry about it.
You are slightly on the small side considering the average is about 6 inches
