I don't know what ManWhore is basing the observation on...but I gotta tell ya,
My sub and love of my life is 5'3" 100 pounds and gorgeous with one of those bright white smiles that most people have to pay big bucks for. She is the one who got me into the "lifestyle" You could have knocked me over with a feather the first time she asked me to tie her up and beat her stupid!
I don't know what the "norm" is...but they are certainly not all fat and ugly!
