But I'm also a hypocrite: I would never date a girl who is bisexual because that means they also sleep with men and men are so dirty that I'd never sleep with a girl who had slept with a man.
Communication is the key and it's one thing I had to learn-to talk to the actors. I was so involved with the visual and technical aspects that I would forget about the actors.
