One of director Brett Ratner's first sexual experiences was with a man dressed in drag - who he initially thought was a woman.
Ratner insists he isn't ashamed of the experience and has written it into new movie Rush Hour 3.
He tells Advocate magazine, "My first blow job was from a man, but I didn't know it was a man. That's where that comes from. It's based on personal experience. It happens to a lot of people.
"That happens to a lot of heterosexuals. You meet a girl in a bar, and it turns out she's not a girl. I think a girl should tell you if she's a girl or a man - that way it's your preference.
"The reaction is "Oh, s**t!" if you're not gay, which is funny, I think."
