I'd like to comment on the picture with the ruler and why do I think it's (to some extend) photoshopped. When you hold your dick like this, erect, look at your unit and what do you see? You'll see skin irregularities, you'll see veins, skin texture and so on. In my case (I'm not cut) you'll even see little wrinkles of foreskin behind my glans. I have to pull the skin back to be stretched.
Look at the finger and hands, you see some of the skin texture, wrinkles on the fingers and so on... but the dick looks totally even in color and texture, exactly like a photoshopped butt from a girl from cheap nude site, sorry.
Oh, actually it is not perfectly even. If you follow the link provided

take a look at the change in color (from light pink to dark pink) behind the glans and also above the thumb. It seems like made from two pictures.
Also look at the hand, the hand is in good quality, you see wrinkles, you see even the hair very good. Not the dick, dick is very blurry...
To sum up, the proof with the rectangles is dubious, but read what I think and than take a look at the picture. And why is that stupid plastic bag on the ruler?
Personally I think it was made from 2 pictures, one bone pressed, one at the glans around 10' mark, then fixed together. The plastic bag is there so the measurements in the middle are not readable > easier to join the two pieces of ruler together.
After writing all this, I think it's 'shopped
my 2 cents.
