I think people see foot fetishists as guys who likes to be dominated and likes to smell pantyhose and socks and shit (and wants to buy them from random women on the internet).
I kinda have FF too, but it's just the shape for me. I think I had it since I was a child. I was very shy about my feet up until I was like twelve, I wore socks all the time, I think feet were sexual for me and that's why I covered them, like I wasn't walking around with my cock out.
