36 [M4A] Ever compared cock sizes? Purpose or accident. Or watch a comparison

Have you ever compared cock size with another guy? Or maybe a group? Alternatively, ever witness such a comparison? Perhaps on purpose, perhaps on accident.

What was the situation? How did it come about? Were there any wagers? How did the comparison go down and what were the results? Were others present?

Please start any conversation with age, sex, and location
