I do not want to sound biased, however when I read feast, I'm assuming you're female? If so I'd say you're on the better side of it. No one really questioning a female buying an intact male. Protection. Best friend. Etc.
To speak directly to your dilemma, I couldn't tell if you were single or not moreso if someone is living with you really. If not, I'd say you're golden. Use the space to TRULY explore yourself as a zoophile. Do you enjoy canine, equine, etc Really take the time to reflect on the fact that you are about to engage with canine penis, equine penis, vagina, whatever your preference is.
Again assuming you're female (and I APOLOGIZE COMPLETELY if you're not), after you've really internalized that with yourself, treat yourself and just go looking for a companion. Pet store, shelter, etc. Notice how I havent mentioned telling anyone yet. Find your breed. Find your preference, think of your life with said partner.
THEN once you've made the adoption/purchase explore yourself then...now that the animal is there in front of you are you still with it? Is it just oral? Do you prefer being fucked etc. You bond, grow, and love your partner. On all facets (this is the fun part)...periodically checking into HERE the community in order to reinforce your holistic confidence.
So FINALLY...NOW...AND ONLY NOW...now that you KNOW yourself, you and your boy have made love countless times, you're secure in him, he's bonded with you, and you HAPPILY bend over/let him feast without shame...THIS is where you can let someone in. Because regardless of outcome, you are solidified. You wont be shamed. Youll brush it off OR youll make a new friend with a common interest!
I suggest the dog park of all places...you'd be surprised, my friend came out to me as a zoo and said he knew I was because I didnt own a dog, but Im always down to come chill when he takes his bitch there...I felt like Spiderman getting exposed. He laughs and tells me not to worry as he points out each girl that's told him they fucked their dog at least once...
So obviously a disclaimer for your area but you know your conversational skills...ease into it. Test the water. Proceed accordingly! Sorry for the long post but I hope it helps. Good luck.
