I had the same size when I was 13 and chances are your pens will definitely still grow, So chances are if you are 6.3 inches at 13 i'd say that you'll have a pretty big pens when you are fully grown:).
There is nothing wrong with having an 8 inch penis, though large for your age just enjoy it.
Well that actually is pretty big for a 13 year old. The average is 4 inches to 5 inches. So your more than average
Penis size usually continues to grow until ca. age 20. 5 inches is the adult average, so 7 inches is already on the large side.
5 inches (which is about 13 centimeters) is the average size penis on humans.
Above Average.
This is actually a little large for a 13-year-old. At this point, the average length is more like 5 inches.
If you are 13, the normal length of your penis should be between 4 and 5 inches.
it SHOULD be about 5 inches. I AM 13 and mine is 6.5inches
While that is 3 inches longer than the average for his age, here is nothing medically wrong with a large penis. It's fine,way above average.I'm 13.5 and I'm 8 inches too.We are both great :)
You can't. Be content with what you have.
Above average, so don't worry!
