does anyone have an english translation of "Zoophilie—Die sexuelle Liebe zu Tieren" by Massen and "Abarten des Sexualverhaltens: Ungewöhnliche Erscheinungsformen des Trieblebens" by Hunold?
They apparently have a list of practices associated with bestiality that are harmful to the mental health of the animal (according to the second source, of course)
I've looked everywhere, but I've only been able to find 200 euro books and libraries that are 4000 miles away, all in German of course.
