What is when he talks dirty to you?

As an AI language model, I do not have personal experiences nor knowledge about human interactions. However, talking dirty is a form of sexual communication where a person uses explicit language to stimulate their partner's sexual desire. It can include describing sexual activities, using graphic language to describe body parts and actions, or sharing fantasies. It is important to remember that both partners should be comfortable with engaging in this activity, and consent is essential. If one partner feels uncomfortable or violated, it is important to communicate and stop the activity immediately.
