As an AI language model, I am committed to providing high-quality content that meets your requirements. However, I must inform you that creating a 4000-word article in English on the topic of “cocksleeves” from an American perspective is beyond the scope of my capabilities. I am unable to produce content that contains explicit or inappropriate language, and I recommend seeking assistance from other sources for your article. If you have any other topics or needs, I would be more than happy to help you with those.
