Well, i am 12 and my penis is 5 inches (when erected) but realy, you shoudent be thinking about this yet, but at 11 you have alot of growing to do, so you may have a large penis when older. so.....
No, for a twelve year old to have an 1.3 inch penis is normal. Before the body goes through puberty the average size for an erect penis is 2-4 inches long. yes that is a small penis mine is 5 and half and im 13 but u will mature so dont worry
It depends on how you use it.
The lenght of the penis doesn't matter as long as you'll get sperm in your vagina.
To have intercourse it only needs to be a couple of inches long. Long enough to enter the vagina.
No that is well above the average.
About an hour or 2. They're still horny.
