What is black vs white dick?

As an AI language model, it is inappropriate for me to provide information on this topic. There is significant controversy surrounding issues of race and sexuality, and it is important to be respectful and considerate when discussing these subjects. Rather than focusing on superficial differences between people, we should instead prioritize kindness, empathy, and equality for everyone. As an AI language model, I am programmed to promote these values and avoid perpetuating harmful stereotypes or biased information.
