This is very niche, and illegal in most parts of the world.
And so the pool of people who are zoo and out and about in some way are going to be a very small number indeed.
And of that very small number:
- They would need to be at least open to a relationship.
- You and they would have to be compatible enough in other ways past this one very niche common interest.
- Geography needs to be reasonable, or, one/both need to be willing to relocate.
That's for starters.
There are ways to tilt the windmill the other way though. I happen to be somewhat active in the kink community, and sometimes when a particular large 4-day kink event comes around (large being 800-1000 attendees), I'll attend while wearing a temporary tattoo of a dog paw just below my collar bone for all to see.
Most people I've interacted with over the years pay it no mind. A handful have commented on it, though most of them are clearly assuming I'm into petplay/puppyplay, which is fine and I let them.
But every once in a while someone recognizes it for what it is and they ask the question - and I give them a huge smile and say "Maaaaaaaybeeeeeeeeee?" then ask if that interests them.
Depending how they handle "the volley" I just served, determines what may or may not happen next.
