Llama 3.1 refusing NSFW requests

Telling me 'I can't answer this as this is against the policy of this platform to create explicit content', however it has written graphic NSFW before. I usually will ask it to write 'graphic' sex and it understands what I want and will comply. 3.3 will do it just fine. Sometimes Deepseek refuses as well, but I prefer the way Llama will do nearly any nasty thing I ask. Why is 3.1 rejecting my requests?
