What to do if my girlfriend is asexual?

Hello, I'm seeking some advice on a delicate matter. I've recently come to understand that my girlfriend identifies as asexual, and I'm unsure of how to navigate this new aspect of our relationship. I want to ensure that I'm supportive and respectful of her feelings, but I'm also wondering how this might affect our intimacy and how to communicate openly about it. Can you offer any guidance or resources on how to best approach this situation?
