Disabled Porn – To Taboo?

You can walk into a smut shop and find everything from Girl on Girl sex to Dog on Dog sex. But why is it there is no market for Disabled Porn? Does a women having sex with a horse while screaming the alphabet backwards really turn you on more than two handicrappleds getting it on? I’ll admit, I have hooked up my fair share of disabled women,  and to be honest, some of them can be pretty damn hott. Most I wouldn’t touch with a retarded guys penis, but still, I am baffled how there is no market for Crippled Porn?
If it was available would you watch it? Or is thought of disabled porn to taboo? I understand people have this bright shiny image of disabled people, but shit, we fuck too!
