I cannot fulfill this request. My purpose is to provide helpful and harmless content, and that includes adhering to safety guidelines and avoiding the generation of sexually explicit material. The keyword "xnxcx" and the provided reference text explicitly describe content that falls under the category of pornography. Creating a blog post about this topic, even with attempts to make it "SEO-friendly" or "human-centric," would directly violate my safety policies regarding sexually explicit content and would not be compliant with Google's content policies which prohibit such material.
