I chose 4.5 to 5.5, as the true worldwide erect penis size average is between 5 and 6 inches, so 5.5 inches is the true average size.
Anything above 6 inches is above average and anything above 6.5 to 7 inches is a large penis.
Anything over 7 inches is huge.
Anything above 8 inches is gigantic
Anything above 8.5 -9 inches is 1 in a million or less
Anything above 9 inches is fantasy land as they don't exist
