Kinsey Erect Size Chart

As for ol´Alfred and his cards: The only thing that´s harder to get than an accurate BP measurment is getting an accurate NBP measurment…

I always have some “give in” when measuring NBP. Even the slightest touch of the ruler/card pushes the skin and the fat in a bit, making it virtually impossible to measure NBP. Of course, you could always make sure the measuring device don´t touch the pad at all…just estimate the length of the part of the shaft that connects to your body. :) Ergo: NBP measuring is like trying to measure the distance from the water surface in a toilet bowl to the edge of the seat without getting the ruler end wet.

Oh, just one more thing that makes measuring toilet bowl depth from the water surface easier than getting a accurate NBP measurment: you don´t have to try to keep an 110% erection when measuring the toilet….:)
