I think considering if your cock is big or small should be based on your height. I know studies have concluded that dick size is not based on height but I just think that if you are a certien height the average dick size will not "look average" due to your height. The below chart should be the standard for considering if you are big or small: If you are shorter than 5'7... Small: Under 4.5 inches Average: 4.5 to 5.5 inches Big: 5.5+ If you are between 5'7 and 6 foot. Small: under 5.5 inches Average: 5.5 to 6.5 inches Big: 6.5+ If you are between 6' and 6'4 Small under 6 inches Average: 6 to 7 inches Big: 7+ If you are above 6'4 Small: under 6.5 inches Average: 6.5 to 7.5 inches Big: 7.5+ This is not what I actually/believe is average cock sizes for these heights... It's just what I believe looks "correct" on a man of a certain height. If a 6'5 tall man has just 5 inches (which is actually quite close to normal for a grown man) then it looks VERY small on him. However if a 5'3 man has a 6 inch dick it looks actually pretty big on him. Maybe its partially about your prior perceptions of what a man should look like when he is naked?
