…STEAM has its own “tricks of the sales”. Some developers release their games through a (foreign) publisher. Others make a censor version of the game (either with NSFW content cut out, or hide everything behind large pixels), and release the R18+ patch for it just separately (and sorry if I’m boring you with this advice, but it’s a really rare-quality game that just has to appear on the biggest gaming platform, plus it will bring you extra income and even fame!).
…I have an acquaintance in STEAM who puts out small thrash games, but he has experience as both a developer and publisher. If you don’t mind - I could ask him about your collaboration (that you at least contacted and just talk about the possibility). I really ask you to think about such an option - because it would be very great and useful for everyone (developers and players)!
I appreciate the suggestion.
Regarding making a non-adult-rated version, that means blurring out almost everything in the game, I thought about it and didn't do it because it's just so much I would have to censor
So distribution via another Channel rather than doing it myself on Steam could be indeed an option.
