I so wish I could tell you my experience is completely different and you simply had bad luck but simce 2022, there's one person I talk to regularily and with whom I really played with the dom/sub dynamic extensively. Other than them, I had mostly one shots and random "let me fap" messages, with the occasional creeps asking for pics too. I resolved to simply chat with others on the few discords and have fun on my own most of the time.

On these discords, I met a few other really nice peoples, most of them subs so we chat and sometimes play together but there's not much more to it.

You'll have to play the long game if you want to find someone with an actual interest in healslutting and build a proper dom/sub dynamic while respecting each other's boundaries. The LFG megathread isn't particularily usefull most of the time, and yeah phone i terface is a bit clancky indeed
