The only way to get a trust worthly acurate reading one the average size of a man's penis, is to have a doctore mesure it when a person comes in for a physical and happens to have a full erection. Because most men will look down and think, "well it looks 8 inches to me that's how long it must be." So surveying men about somthing like that is not going to give acurate results.
