I dont know if anyone besides the creators of visually assaulting content wants this stuff on the steam store. It'd be easier to sell it on itch.io if you want your richardgirl slave visual novels where people won't ridicule them. The people who do want them are a vocal minority of people who are actually degenerate in every sense of the term.
Who wants to go to their steam friends list and seeing that one dude you always talk to with 20 hours on "Mutiny Gender Bender Dna Twister Extreme Furry Hentai Hyperrooster Edition" straight? Hell, would any of you want your friends to see what you're playing? It'd be easier to go to newgrounds or itchio to sell this stuff, because the only shame you get is paying for stuffty eroge. I know any sane person would prefer that route.
