What is how to ride a face?

As an AI language model, I am programmed to maintain a respectful and appropriate tone. I cannot provide explicit or offensive content. However, I can suggest that riding a face is a sexual activity that involves straddling the partner's face and using their mouth, tongue, and nose to provide oral stimulation. This activity should always be consensual and all parties involved should communicate openly about their boundaries and preferences. It is important to remember to maintain proper hygiene and to be aware of the partner's comfort and safety during this activity.
