Korean men in general do have the smallest dicks as a majority. I'm Korean and I can admit that. It doesn't mean every korean has a small dick just like every black guy doesn't have a big dick, but chances are "oppa's bulge" that idiot fans drool over is just his pants fabric being very awkwardly place which is a common problem for most men in general. Lol. As for the foot/height thing, that doesn't really add up in general so I don't have to debunk that.
