Is it erect or non-erect sizes?

That specific chart is erect. There are others of non-erect on google.

Seriously though, people shouldn't be ashamed to be shown as having small penises on this chart. Well... Maybe if you are Korean. 🙄 But that is not your fault if you are. It's mostly caused by the dictatorship that has ruled North Korea. Not allowing contact with the rest of the world has lead that country to have malnourished children. The smallest in the world, even. Most of them die at young ages. Small people will have small penises. 

I agree. Men shouldn't feel ashamed for something they cannot control, much like how women shouldn't be ashamed of their body proportions either.

I be honest under 5 inches and I am not amused

Problem is that is about the biggest a regular US condom would get due to stupid laws that make no sense.

I find black guys are usually bigger then average :)

I don't even know my size. Since all I use it for is urination and masturbation, size is somewhat irrelevant.

Size with stamina is a lethal combo :)

I kinda think the same but speaking about color people I find black women have usually bigger breasts than average. 

That's a lot smaller than I expected. Probably because porn only shows us the big ones.
