Fetish I don't know, but I think a lot of them do like a bigger cock. Back in the day I had an Asian girlfriend and she had a Asian friend who was first and long-time partners with another Asian guy. Women like to talk about cock size, so one day it came up and my gf told her friend that I had a 7" cock. Her friend was a little shocked/confused and said that her boyfriend had a 4" cock that he was quite proud of. At one point I was even asked to pull out my cock for her so she could see it. A few months later, for various reasons, the friend had left her boyfriend and soon started dating a white guy, cock size unknown.
