One of my best friends had one of the biggest cocks in high school. He once told me he used to wish his cock were smaller, more average. All there guys teased him, calling him "Donkey Dick" and "Horse Cock", etc., and the girls were afraid of it.
However, later on, when he found older girls really liked it, saying how much better it was than thesmaller dicks of their boyfriends, he started to really enjoy having a big dick.
He screwed a married woman down the block. Her husband was a marine on a tour of duty in the Middle East. She said it was much better with his big dick than her husband's small five-incher. We used to drive past their house. One day he said, "There he is!" He was really good-looking, muscular dude out mowing the lawn. Kind of a turn on to hear he was under-powered like that where it counts.
I myself am tall, well-built and hairy chested, but hung like a chipmunk. Soft, it's almost buried in my pubic hair. (Big balls, though!) Strangely, I hardly ever got teased about my size, and then mostly in a goodnatured way.
I should mention that my friend's comments about girls apparently preferring big cocks like that really did add to my insecurities about my size at the time (and for a long time thereafter), although I never let on. I later wondered if he was conscious of how it affected me.
