Thanks for replies
For example, in my case, diameter is not related to circumference. Diameter of head and base measures above 2 inch wide ( 2.15) and my circumference is only 5.75 to 6 inch.
Yes...but the AVERAGE of various diameter measurements of your penis from different angles
would be directly related to circumference. In any case, circumference is the accurate way to gage girth.
For total dick size, you need to do a calculation based on the volume of a cylinder. So, take the circumference and divide by PI (approximately 3.1415) to get the average DIAMETER. Divide DIAMETER in half to get the RADIUS and then SQUARE that number, that is, take the RADIUS to the SECOND POWER. Now multiply that result by PI. This number is the surface area of a circle, that is, any given cross section of the cylinder (your penis in this example). Take that number and multiply it by the length or height of the cylinder and you have total volume in cubic inches (presuming the measurements are in inches or fractions thereof).
Familiarity with this formula will drive home the fact that in total dick displacement, girth is more important than length. Think straw versus soda can. The straw is twice as long as the can is high, but the can have volume many times that of the straw.
So...the average dick is 10 to 12 cubic inches. Hung men are 18 to 30. Horse hung men are 30 to 60 (yes, these rare breeds do exist: 12" x 8" is about 60 cubes). Pencil dicks are anywhere from 2 to 8.
The most amazing thing is the variance in size between men. No other part of the human anatomy, male or female, varies so greatly in size between individuals as does the penis. One man may have a penis six times larger than average and one may have one only a third the size, for a difference of almost 20 fold.
