No you are wrong. Asian girls don't have the tightest pussies. It is well known that the Inuit Eskimo girls have the tightest pussies in the world by far.
I've only been with 2 asians and they were pretty tight. I think they are like any other woman though. I have heard black woman aren't as tight and the one I was with was tight. so I guess it just depends. Nuthing beats latina pussy though
What's a Nubian? Aside from that no the rumours are false and Blue Balls North Korean women have the tightest pussies where else are they going to keep Kim Jong's weapons of mass destruction aka his crabs
