I've never known I had an above average sized cock until quite late in life. Once I did get curious (due to a girlfriend's assertions) I remarked on it to a friend I've known since pre-school and who I would tell anything. No sexual interaction involved, we both got hard and compared - for his satisfaction, more than my own. He says he's a little over 6" and most girls he's with tell him he's packing a big tool. Mine looks HUGE when next to his. It's only 2" or so difference, so WHY does it look so much bigger than just 2"? As I'm only 5.5" girth, his looks fatter (although it's actually less, but that's the optical illusion of length v breadth). I'm finding it hard to understand why only 2" difference makes it LOOK twice as big.
