As a child, I had walked in on my dad in the bathroom once or twice, prompting my mom to give me "the talk," so I wasn't exactly a stranger to the male anatomy.
One day, though, I ended up playing doctor with a friend of mine and found that his penis was a lot smaller than my dad's, both in absolute terms and in proportion to the rest of his body. I knew from TV that having a small penis was something to be ashamed of, so I teased him for it for years. It never occured to me that they grow the way they do
