Ellen DeGeneres: Diane Keaton on Wine, Tantric Sex and Marriage

It's funny to watch Diane Keaton as she laughs her way though an interview on today's Ellen DeGeneres Show. The star stopped by to talk about her new movie, The Big Wedding, and while olding a big glass of red wine on ice, she explains that her character is into tantric sex. When you have tantric sex you go for a long time and you have that thing called the orgasm," she explained, "for nine hours! For nine hours! That's ridiculous!" Keaton breaks into hysterics on both shows explaining tantric sex and her role in the movie.
