Yeah, it's totally normal, we fuck donkeys, dogs, cats, cows, geez, you name it.
Okay, let me clear a few things up:
Jesus, fuck no, it's not normal and we don't see it as that. Fucking donkeys is some kind of 'tradition' (if you want to name it like that) between the north region hillbilies and peasants, and people with no education whatsoever. Dads and most of the society here are kinda sexist. At some age, they take their sons to the brothels to make them 'a real man'. Sometimes they leave in the middle of nowhere or there's no brothel around and they fuck a donkey, simple as that.
This makes me sick, basically because I'm from that region.
