Your diet affects everything: Sleep, mood, weight, heart health, and your libido. But these 11 foods will help revamp your relationship. Soya Who knew that steamed tofu steak might turn you into a horn dog? Soya products like tofu and edamame contain phytoestrogens, which basically mimic the effects of estrogen, the chief female sex hormone. Oysters Consider this one a double-whammy. Not only are oysters thought of as an aphrodisiac (the smell of salty ocean air alone turns us on). They’re also extremely rich in zinc, which helps with the production of testosterone, says Wissing, which boosts sex drive and your man's sperm count. Raw bar date, anyone? Dark Chocolate Like oysters, many say dark chocolate is an aphrodisiac… all the more reason you two should indulge in the occasional after-dinner dessert in bed. Chocolate also helps release the mood-lifting hormone serotonin in the brain. Happy plus horny and you can count on a good roll in the hay. Ginseng Tea Finally, good news for tea-lovers. The compound ginsenoside in ginseng tea is believed to increase sperm count due to its effect on the gonadal tissue. The tea isn’t only good for those little swimmers; it's also believed to improve his desire to get it on. Hot Peppers According to nutritionist Kimberly Snyder, hot peppers don't only make your upper lip sweat. They rev your engine, too. The peppers are believed to speed up your metabolism and increase the blood flow to your nether regions. Not to mention, if your cheeks flush from the spice, someone might think you’re flirting, which can only improve matters. Garlic Forget about bad breath. The compound allicin in garlic is said to thin out the blood, which improves circulation, which means open arteries, which ultimately helps with healthy boners and serious stamina. Asparagus Funky pee smell? Whatever. According to docs, this green veggie is rich in folate, which regulates the production of histamine, a chemical released during orgasm. Can you say aaaaaaahsparagus? Watermelon Hopefully he's not battling impotence, but it can't hurt to nosh on this sexy fruit. A study done at Texas A&M's Fruit and Vegetable Improvement Center found that watermelon has a Viagra-like effect on the body. One of the many nutrients in the fruit is citrulline, which breaks down to relax blood vessels and possibly prevent erectile dysfunction. Leafy Greens The last thing you want to be is anemic, a.k.a. iron deficient, and falling asleep instead of making magic under the sheets. Get your iron fix with beans and leafy greens, and make sure to pair those veggies with Vitamin C (red and orange bell peppers and citrus fruits, for instance) to increase the iron’s absorption, says Wissing. High-fiber Carbs You carbo-load pre-marathon, why not pre-marathon sex? Embrace the healthy carbs like whole grain bread, quinoa and barley so you have the energy to keep going all night long. Fatty Fish Penises and vaginas require a healthy blood flow. Fortunately the fatty tuna and salmon wrapped in your sushi lunch is packed with Omega-3 fatty acids, which help with circulation. And Strong circulation can help increase the effects of clitoral stimulation.
