I only discovered CHYOA a few weeks back. I do have a long history of writing short erotic fiction on tumblr or doing erotic story chats and thus inventing stories together. I was looking for quite a while for something like CHYOA, and I dabbled with systems like "Quest", but most of it turned out to be actually too detailed and complicated for what I had in mind: I wanted to focus on the story itself, but add some variables and conditions to sometimes "force" the reader into certain paths, creating a real sense of immersion. When I found out about CHYOA, the new system of variables had already been set into place, and it was exactly what I was looking for. So far, I have plunged myself into one story ("Happy Maid"), and I have great fun with it. I am also impressed about the community so far, because I got quite a few messages, replies, comments and remarks. I really like that. I still want to open it to general contribution and experience even more of the community feeling, but at the same time, I have quite a few specific details in my head on where to take the story, so I am still reluctant.
I am not a native English speaker, so my texts will often probably sound a bit "rough" and not as smooth in terms of vocabulary and grammar as they would in my native language, but so far people don't seem to mind, so that's great.
Looking forward to working more with all of you.
