itch.io

Last I checked, Booth (BoothPM? It's partnered or owned by Pixiv?) allows NSFW comics and games. I feel like your VNs and Comics that have been translated to Japanese would do really well over there! Other than that, the options are pretty slim aside from just making your own personal site and host it on somewhere like NeoCities or something.

I saw this post saying that JAST was open for contact in this regard - the initial post mentioned BL and otome games, but I included a reblog where the same person mentioned those were not the only categories they were open to receiving.
