I don't know about that, when it come to animals hentai, I only think about animal girls, like half human half animals, I think it called kemonomimi, for example Hatsuse Izuna in 'No Game No Life'. And about white people have sex with animals, I believe it called furry, right? As far as I know, the animals that they want to have sex with, are like 95% animal and 5% human, like a cat with limbs like human and that's all, everything else stay animals(female animals often has human boobs too, but I think it's only for making them fell more human and more attractive), so I don't understand white people to the fullest but I also into pokemon being humanize like Gardevoir or Lobunny, is that the same?
