I agree with genitals looking shitty in games but I never thought censorship fetish was a thing.
I wonder what people who have that fetish thinks of while masturbating to censored porn?
People have such weird fetishes, I guess I'll never understand some of them.
You have to try to enter the mindset of a person sometimes, though your milage may vary. The way I see Corkforthecause's reply is, the mind fills in the blanks for what should be there realistically. The premise may be that for people who enjoy both real and animated porn and prefer real anatomy, the stylized (and often conveniently shortcutted) cartoon / anime anatomy doesn't feel sufficient. If it's censored instead of explicitly shown, the person doesn't get distracted by the inaccuracies of the anime version.
It's not typical but that's the approximation I can only guess from the user's posts. Nostalgic influence psychology can make people do seemingly unintuitive things to get a sensation of something they enjoy from another place or time.
