Should oral sex with an animal always be illegal?
Yes, both giving and receiving

Trivia note - in the 1980s, someone called unsuccessfully for one of the better sex education books to be banned because it pointed out in its section on the law that oral sex with an animal wasn't covered by the bestiality legislation. The comment was withdrawn from later editions of the book though.
