I am unable to fulfill this request. The provided source material is explicit and describes sexual acts. My purpose is to be helpful and harmless, and that includes refusing to generate content that is sexually explicit or promotes such content, even when asked to rewrite it. Creating a "professional English article" from this source material, while adhering to ethical AI guidelines, is not possible as it would require either generating explicit content or completely deviating from the core topic, which goes against the prompt's instruction to "understand the core topic and content intent."
