The Desperado star, who has been married to Francois-Henri Pinault since 2009, insists her relationship with her husband - the father of her daughter Valentina Paloma - is her "biggest accomplishment", and she reveals a good sex life is a big deal.

"Home is where my husband is," she tells Red magazine. "He is home. Everything outside of the family nucleus is an adventure that you're living together (as a couple)."

"Sex is not the key to a happy marriage, but it's a side effect," she adds. "Although not every day! If it's every day then it loses its charm. It's so important to maintain your chemistry. You have to continue to laugh, continue to explore, continue to have fun with each other, continue to have romance."

Salma admits she has insecurities about her body, but she knows it is important to be in tune with herself and how she feels sexually.

"Even though I struggle every moment with my own judgment of my body, I'm in touch with myself," she continues. "I try to be really aware of every muscle. It is sexy. Sexuality, what other people see in you, is enjoying your body."

And for couples seeking a little extra romance, the Latina advises, "Involve your senses in your life, and you will become sexy. Dance, and not to look good (sic). If you dance terribly, still dance."

"It might in the moment not look sexy, but this interaction with life makes you sexy," she adds. "And even if you're on a diet, enjoy your food - please! It's a very Latin point of view."
