If it fits in my mouth without effort, it's small.
I think both length and thickness plays into a penis being classified as "small". I think under 5" in length is small in general, but if a 6" cock is very thin I consider it small as well.
I feel my own is on the borderline of small due to its slender girth.
lol well for the next question...how much can you fit into your mouth without effort?
I think I'm going to go with the general consensus on dimensions... I was thinking 'corn dog' when trying to determine length and girth, but I didn't have one handy, and was unable to locate measurements on the web...
AH, but which size corn dog? Safeway or Costco size? *wink*

...At least once in my life, I'd like to come across a guy that matches me or bigger, if not once. Still, small guys are fun.
