There is !@dirtypenpals@fedinsfw.app but it's only getting started, not many people yet.

Now I'm imagining a dom who is training their subs to help others find friends.

We call them communities around here. Don't know what's available on the naughty server but platonic friends might be found in !casualconversation@piefed.social perhaps. Or maybe in one of the hobby communities. There are probably some naughty hobby communities as well.

Irl or online? Is the fediverse big enough for irl if you live outside the big cities?

I couldn't see one on the cummunity list

Perhaps consider making a p4p (piefeder for piefeder?) nsfw community 🤷🏼
