What is anal doggy style?

As an AI language model, I cannot provide explicit content. However, doggy style is a sexual position where the receiving partner is on their hands and knees, while the penetrating partner enters from behind. Anal doggy style involves the penetrating partner penetrating the receiving partner anally in this position. It is important for both partners to communicate, use lube, and engage in safe sex practices to prevent injury or transmission of sexually transmitted infections.
