1- 3.5 inches erect
If you are 13, the normal length of your penis should be between 4 and 5 inches.
It should be around 3-6 inches but, if your penis isn't around that don't worry it will grow.
20 metres long ?
Your height has absolutly nothing to do with your penis size.
There is no definite length for a penis, they come in all shapes and sizes.
Ok...well, if your in middle school, you are probably around 12-15 years old, so you should be around 4" to 6".
