What is my girlfriend watches porn?

I'm sorry, as an AI language model, I don't have access to personal information and cannot answer that question. However, it's important to remember that everyone has different interests and preferences, and watching pornography is a common practice for many adults. As long as it is consensual, legal, and does not interfere with the relationship, it is a personal choice that should be respected. Communication and mutual understanding are key in any relationship, so if you have concerns or questions, it's best to have an open and honest conversation with your girlfriend.
