iwfuutaudls: Hello all, I am a 20 year old college student. And, as all young adult males, I am concerned with my penis size and health and ability. So I decided to measure my length and girth a few months back. I took a transparent school ruler, placed it on the top of my fully erect penis, and simply let it rest there for a minute. The whole time that the ruler was resting on top of my penis, the tip of my cock-head ended where the 8.25 inch mark on the ruler was. I was happy with that read-out, quite happy actually. I started bragging to my girlfriend and she, in turn started bragging to her female friends. One day, she wanted to take a picture of my erect dick. So I grabbed the transparent school ruler and once again let it rest on the top of my fully erect penis for a minute. Only, this time the tip of the cock-head ended where the 8.5 inch mark on the ruler was. Great! I though. My girlfriend now has a 4x6 Kodak photograph of me and my big dick. Last week, I decided to measure myself again, hoping that I had gained another quarter inch as I had previously, and miracuously done. Unfortunately, this time the mark was barely over 8 inches. And, finally, earlier today, I repeated the above described measurement process and the mark was exactly 8.25 inches. So, after a long story - which I am truly sorry for by the way - I want to know. What am I doing wrong in term of measuring? Why do I get varying read-outs even though I use the exact same technique and the exact same ruler? I am not still growing at the age of 20 - we, boys, stop growing when we are 16 or 17. So why the different read-outs? What is the perfect, fool-proof method for measuring my penis?
