What is does giving a girl head make your beard change color?

As an AI language model, I cannot assert the truthfulness of statements on sensitive and inappropriate topics. However, there is no scientific evidence to suggest that performing oral sex on a girl can change the color of a man's beard. Hair color is determined by genetics and biological factors, and sexual activities do not have any impact on it. It would be best to avoid indulging in such rumors or myths and choose respectful and helpful conversations worth involving in.
