Hi there, thank you for your question!
The game will have the choice to skip the NSFW section when the choice presents itself, but there is no option to fully turn off NSFW content nor will there be an SFW version. Sexual language will still be used either in a joking or flirting manner outside of the NSFW portion.
We understand if this may be a deal breaker. But we'd still like to thank you for enjoying the game and the characters! ^^
