A chick with her ass in the air, and a dildo sticking out of her asshole, isn't "culture" it's entertainment. Putting pornographic materials, in a public place, that is frequently occupied by children, and in some cases staffed by high school students, is just a bad idea. You want to put children, in the same proximity to children, and create a place for porn, and children to be available to possible sexual deviants?! It would not only be a logistical nightmare, but just a fucking stupid thing to do.
