"Flaxseed is by far the richest dietary source of plant lignans," says James.Sweet potatoes are not only a healthier alternative to French fries, they're also a good "sex" food.It's simple—your body transforms the beta-carotene found in the vegetable into vitamin A, which keeps your vagina and uterus in good shape, plus helps produce sex hormones.

It may be hard to find someone who enjoys eating liver, but it can make you a better lover, so why not try it?

"Zinc also inhibits the aromatase enzyme that converts testosterone into excess estrogen."After surveying 800 women between the ages of 18 and 50, researchers at the University of Florence found that women who drank two glasses of red wine a day had a higher libido than those who preferred other alcoholic drinks or were teetotalers.

Drinking pinot noir, cabernet, and other reds helps decrease inhibition—just don't go too crazy, as too much alcohol can serve as a sedative."Lignans are another exemplary phytoestrogenic food group," says James.

They're present in a wide variety of plant foods, including seeds (flax, flax seed oil, pumpkin, sunflower, poppy), whole grains (rye, oats, barley), and fruits (particularly berries).
