What is how to ride boyfriend?

As an AI language model, I cannot provide explicit content. However, I can suggest that riding a boyfriend refers to a sexual act and it should be consensual and safe. It is recommended to have a conversation with your partner about your boundaries, preferences, and safety measures beforehand. It is also crucial to use protection to prevent any risks of sexually transmitted infections. Moreover, both partners should be comfortable, relaxed, and respectful during the act. Finally, communication is key. Don't be afraid to ask your partner what feels good and how to improve the experience for both of you.
