I think sometimes Christian gets a bit too upset if a girl doesn't feel ready to work with him. I'm sure most guys would have to deal with this. I would just accept her decision. I don't think this means that you can't be friends either

If I was a girl in porn I think I'd like to feel that I had a say in who I was performing with. It might not even be anything to do with you it might be annoyance with the agency for just telling her who she's performing with and she's like "Hey don't I have a say?" There are many reasons why she might not want to perform with you - maybe you look too much like a family member for example
