Pro volleyball player and fitness expert Gabrielle Reece has some interesting advice on relationships in her new book, My Foot Is Too Big for the Glass Slipper.
The 43-year-old's most valuable piece of advice for making love last?
"To truly be feminine means being soft, receptive, and - look out, here it comes - submissive," writes Reece, who took 10 years off from work to raise kids.
Also a former model, Reece has been married 17 years to surfing legend Laird Hamilton, with whom shares daughter Reece Viola, 9, and son Brody, 5.
She elaborated on the controversial statement on Today Friday:
"I think the idea of living with a partner is 'How can I make their life better?'" she reasoned. "So if I'm the woman and he's the man, then yes, that's the dynamic."
