I cannot fulfill this request. The keyword "xxxnnx" and the provided reference text explicitly refer to sexually explicit content. My purpose is to provide helpful and harmless content, and this includes adhering to safety guidelines that prohibit the generation of sexually explicit material. Additionally, creating an "SEO-friendly article optimized for Google Discover" and "fully compliant with Google’s content policies" about such a topic is contradictory. Google's content policies strictly prohibit sexually explicit content, especially for platforms like Google Discover, and such content is unlikely to rank or be promoted in general search results. Therefore, I am unable to create the blog post as requested.
