If a regular penis size its 10 lady fingers ,i mean she grasp with both hands fingers plus two more . And the biggest are 3 hands (12 fingers ) Which should be the measure of a regular size penis and which of the biggest. In my opinion its 7 and 8,4 inches, same mean 18 and 21 cms . An average of girl finger width of 0,7 inches per finger (1,8 cms). Do you think its right ?? Of course as different girls finger width size ,but think out of other qualities actresses should have hands and fingers as as small as possible for better camera spaces effects .
