I had never heard of this until just now.
I Googled it and some porn came up. I couldn't believe how small these guys dicks were, even when they got hard.
But what was really surprising was that these were normal size guys. Stereotypically small dicks are associated with Asian guys but these were normal size white guys, you'd never guess they had dicks smaller than my big toe.
The one common factor they had was that they were all chubby and soft looking.
