Don't like equines at all. and birds are cool, sometimes cute but rarely sexy... so I prefer them strictly as bottoms.
Low-class, low-trust, 'earthy' and degenerate types of anthro males get me hard as diamonds. Hyenas, Coyotes, Raccoons, African wild dogs etc. Fucking dudes are spicy af... bonus points if they REEK of body odor and are sadists and/or masochistic.
