To be clear on my view of cuck/sharing/3 letters cursed word....
Those are either a fetish that you find in a game (made for them or not, nothing wrong with it) OR a punishment/consequence of your actions(like I view it).
Like not pursuing a LI, being friend with benefit so maybe having to share the LI or just being stupid/bad/too lenient and having the LI snatched away from you (in Babysitter with Christine for example).
All of this to say I don't mind having cuck/sharing/3 letters cursed word in a game not made specifically for those fetishes if they are avoidable or a legit consequence of my actions ; cause who else can I blame but me if a LI not pursued goes to another or if a guy corrupt a LI without me interveening ? It's part of the coherence of the story, to me at least.
Edit : that said ; I'll be shorter in saying what I
feel about those fetishes (getting off of 'em, caring about their presence in a game) :
