The ONLY valid way to measure your dick length is to take an old-fashioned wooden school ruler, place it flat on TOP of your dick, and push it into your pelvis as far as you can. Looking down from above, where your dick ends is how long your dick is.
I've never heard of this method before. Does it really make sense to "push the ruler into your pelvis as far you can," considering any additional "length" gained by digging the end of the ruler into the fleshy, in some cases fatty, part of the pelvis above the penis isn't really useable length?
Also, a tip of my own: If you have a high erection angle like me, bend your unit down so it's horizontal before measuring. This will easily add 1/2" to your measurement and more often than not, is a more common intercourse position anyway. I only discovered this fairly recently and it did wonders for my self-esteem (yes, it's kind of humorous how we guys stress over fractions of inches).
And completely unrelated: Is it just my crappy computer/monitor, or does every page CutCaliGuy posts on become abnormally "wide" so that one has to scroll horizontally? My monitor resolution is at a humble, but pretty common 1024 x 768 pixels. I think it may have something to do with his sig.
