I am in the same boat as you guys with respect to perspective. I am 6' and 250lbs (give or take), with fairly thick hands (13.5 ring size) and big legs. My perspective is off, and not having another dick around to compare it to I have a different view of big. That being said, when I see my cock on cam, or in the hands of a woman I can appreciate that it is fairly big. And feedback has been supportive of that, but still, I think that it is the nature of our being to feel (in most cases) that we are somehow smaller than the next guy.
