It’s very common in BDSM for Dominants to call their submissives b*tch, c*w, pig, and other names meant to animalize them. Animalization is a fetish — perfectly legitimate inside the scene. That’s how it is.
But I also like thinking of the Dominant as an animal: a beast, a hunter after his prey, acting on instinct. I like the idea of a Dom whose voracity takes over — as if his drive to breed were something that outruns his reason.
And I know that you, as a submissive, also like seeing yourself in that role: the hunt, the prey seized by the beast that eats, by the voracious animal that swallows you whole.
What’s interesting is that animalization cuts both ways. It can be pointed at either role. In each one it just takes on a different meaning and a different purpose.
