In my limited experience so far, it can be pretty difficult to find local zoos, and almost impossible to find any willing to help you with contact stuff. The fact is it's incredibly risky to invite people for that kind of thing so there needs to be absolute trust.

The best place to start would probably be online communities where you may eventually learn about some locals. But definitely don't expect or ask for experiences right away, that's a surefire way to make everyone distrustful of you and think you're only interested in sex.

I'm really only just starting my journey as well. Part of me hopes that I don't actually find any locals because the fewer people that might know who I am the better.
