Zoophiles love their animal partners sexually, emotionally, and romantically in much the same way a human loves their human partner.
Bestialists like having sex with animals. They can view their animal partners as close friends, just pets, or (sadly) simply a living sex toys.
Fetishists get off on watching and imaging but would never actually do the deed.
So, based on the limited information you've provided...maybe? Probably not though, because emotional and romantic feeling wasn't mentioned. But there's nothing inherently wrong with being a beast, so long as you take proper care of your partner. Also nothing wrong with simply liking the porn. Provide more information and we can better pigeon hole you into a textbook definition. ?
