Welcome to the Forums,

Is this for fantasy or are you serious?

Are you seeking to have sex with the animal, is this for your partner, or do you want to watch?

Your location, country, state, etc. will determine the legality of this type of encounter as well as any materials depicting bestiality.

We could have, and I'm sure there are, links on this site discussing the "consenuality" and medical issues between human partaking in sex with animals.

Do a few key word searches and you'll find some members of this site who claim to be into this type of fetish. A private message with a few serious questions may provide you with more answers than people are willing to post in public.
