Mental illness can happen to anybody. You can be a dustman, a politician, a Tesco worker... anyone. It could be your dad, your brother or your aunt.
I think people are born bisexual and the make subconscious choices based on the pressures of society. I have no question in my mind about being bisexual. 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.
There's a continuity between what I care about in any form: I care about it in my music, in article-writing, in how I dress, in how I live, in my relationships, in how I navigate paparazzi, how I decorate my home. There's such a continuity between everything that I don't really care what form it shows up in.
