This is where a separate perv persona for online ... whatever ... comes in handy. It's why I would never buy such a game on Steam(or at all, but that's just me, and far from advice I would give).
Just give an answer in-character, not an IRL one.
Yes, I may play a standard murder-hobo in games, but I would still like to be able to do a guest appearance on my kids' or a friend's Twitch/whatever streams without some one digging and sharing with them that I had collected a trophy/achievement in Murder Harem: Furry's Vore Safari Edition, or even the vanilla crap I am actually even slightly into.
Good news! You can buy Murder Harem: Furry's Vore Safari Edition (if that's what you're into) on Steam and nobody would ever know as long as you mark it as private while it's in your basket! Assuming it works as they say you'll still be able to play the game as normal but nobody else would know unless they directly log in to your account.
The faq doesn't mention the new Steam Family stuff though. I'm guessing it'll at least be hidden for parent accounts, but since parent accounts can control game access for child accounts that might not be as private?
Game Mechanics wise? No idea. Porn wise?Well, it sure sounds like it wouldn't be vanilla.
I have no interest in finding out what's even less vanilla than Beastiality Vore. That's the "Safari" part; I'm not trying to imply that furries are all into literal beastiality.
