During an appearance on The Late Show, Chaz Bono and David Letterman discussed the differences between gender and sexuality.

Bono, the daughter of gay idol Cher and the late entertainer-politician Sonny Bono, announced last year that he was eight months into gender reassignment.

Bono's transition is documented in the film Becoming Chaz, which premiered Tuesday on nascent cabler OWN. He's also written a memoir on the subject, Transition: The Story of How I Became a Man.

“I confused my sexual orientation and gender identity,” Bono told his host.

“You have encapsulated my confusion,” Letterman replied.

“Sexuality is who you're attracted to. It's about other people,” Bono explained. “Your gender identity, I like to think of it as having really two components. There's obviously your physical body – your sex – but there's also how you feel inside, or the gender of your brain. And for transgender people, those two things just don't match up. So, always inside I felt male. From the time I was a little kid I felt like a boy, but obviously had a female body.”

Confused, Letterman asked, “Is this connected to homosexuality?”

But he then managed to confuse Bono by asking, “I grow up and I'm a boy and I'm attracted to women, but is it possible that I could feel like I was a woman trapped in a man's body, and still attracted to women? So, I'm not homosexual at all?” (The video is embedded in the right panel of this page.)
