"New in-house standards that limit sexually explicit content distinguish Sony from other game-hardware makers that allow more leeway as long as the software carries a rating from a national industry body," The Wall Street Journal reported late on Tuesday.
The move is reportedly aimed at helping developers "offer well-balanced" content that does not "inhibit the sound growth and development" of young people.
"Sony is concerned the company could become a target of legal and social action," a spokesperson for Sony in the US was quoted as saying by The WSJ.
The rule appears to have hit a number of titles already, including the "Devil May Cry 5".
Sony's home turf of Japan has a reputation for having a higher tolerance for erotic games -- games that might be considered risque, or outright offensive, in the US.
Whatever the exact rules, some developers aren't happy. There have been instances where developers had to cover up characters using light rays, smoke or similar effects, and there's a fear this will curb creativity among developers.
