some, at the least, are. Beastiality seems to be a default depictions of the principle of sex in life; It's always there, like a pet or animal comes when it wants to and is generally out of sight. Just think, if you had been a character playing a minor role "a beast", although it ends up being an animal it is the character available and without much character to develop likely isn't doing much else anyway, so get a brother some work, i guess. Some people are really into it too.
