"We have this idea that you can't be a mother and a businesswoman and like to have sex! How is an intelligent woman a sexual being?" the 43-year-old star tells Self magazine. "It's really hard to integrate those things. Like, 'Gwyneth has sex? Really?' It doesn't seem to go together."
Paltrow -- who looks sensational on the cover of the fitness magazine -- adds, "But I think it's important, as mothers and as women contributing to society in whatever way we each are, that our true sexuality doesn't get lost or put aside."
She's also been very vocal about having an amicable relationship with her ex, Chris Martin, and the secret to co-parenting their two children. "You have to constantly let go," she told ET. "You have to let go of old ideas, old resentments. You have to put the kids first, which I think people have the idea of that, but then oftentimes, you struggle with it."
