What is the "official" measuring technique?
I noticed that if I measure erect length with a cloth tape or a string I get a larger number than if I measure with a ruler. The reason for this is most likely that my member has a downward curve.
When measuring with the ruler the measurment is more bone pressed too, since it´s easier to push a hard ruler into the fat on my lower belly, than it is with a cloth band.
These two measuring techniques are quite different: With the ruler you can bone press but you can´t follow the curve. With a tape you can´t bone press, but you follow the curve all the way to the urine opening.
Here is my question: What is the “official” (if there is such a thing) measuring technique? Should one use a ruler or a tape?
