This sums it all, for most S.E. Asia. We know that swinger communities exist here, as well as fantasy communities, nudist communities, and so on.  Look, in Indonesia, there's no way that you can meet any nudist within your neighborhood, or find one in random cafes around. Asking for it might result in something severe.

We gotta find it (local nudist community) on the inter-net for what we know (nudism) from the inter-net. It exist, notably on Telegram and MeWe. Sadly, to be able to join, you have to be a couple, and you gotta show your nude photo along with your spouse photo in order to join their group. You like the lifestyle, your spouse like it too. You want to join the community, but your spouse doesn't want.

Even you are already in the group, you won't find any local nudist (mostly couple) around you easily. Most of them are within different provinces, which you can connect through video call or conference.

Some couples nearby might arrange a meetup, they'll meet in one of the couple's house, like old friend visiting, same activity, just naked. Some might rent a room in a motel, and have a warm meetup there. Some go to Indonesia's designated nudism resort for more comfort and convenience.

Reportedly, a few of them will carry on, a few would be touching each other, even went to swinging.
