I can share my experiences, when i was looking for nsfw communities where there would be conversations/discussions around topics of kink/power exchange etc. it was a difficult search. Most nsfw discord guilds lack a well defined purpose, they are often built around the pursuit of quick gratification rather than exploring kinks/sexuality in a more comprehensive way. There were a few healthy communities but they were in a different part of the world and the cultural differences were huge. I wish people would build communities around conversations instead of just sharing porn/gifs.
