Roseanne writes about her riff with Oprah in her third book, Roseannearchy: Dispatches from the Nut Farm. The book also touches on Roseanne's three failed marriages, her body image and her sex life—or lack thereof.

Roseanne says sex is not that big of a deal. "It shouldn't be the subject of every single television show, the center of everybody's life." she says. "It's not that cool. It really, really isn't. People who have sex and talk about it all the time are not that cool either."

Watch Roseanne talk candidly about sex??  

And, whatever you do, don't call Roseanne a cougar! "That makes me want to upchuck," Roseanne jokes. "I say I'm a badger—I kind of hide in the dark when there's any kind of threat of anything sexual coming my way. I'm old, I mean seriously."
