So I've noticed this Fetlife mentioned a few times and a search on here doesn't throw up too much other than it being more of a shared interest group rather than any type of meeting place.
That's pretty much exactly what it is. Think of it as Facebook for people into kink.
If you'd like to explore, I'd suggest checking Fetlife to see if there are any local kink meetups ("munches"). These are usually strictly social-only, no "play"! The idea being that you get to meet with like-minded folk and socialise in a relaxed but kink-friendly atmosphere. There are sometimes talks, workshops, trade shows, etc. too.
Obviously, the current pandemic means that most in-person activities are on hold, or have gone virtual-only.
Make some friends and demonstrate that you're not a serial killer, and who knows what doors may open up.

Good luck!
