My co worker is thinking about trying a white guy

I have been working on my co worker and telling her the white guys can do it just as good if not better than the black guys. I am going to need your help to truly persuade her. But she is thinking about it, her thing is if she did it, it would have to be someone who she doesn't know. So that means I'm out of it, so she thinks. Lol! I will be showing her this depending on the responses.
