1. Oysters

Considered to be a powerful aphrodisiac since ancient times, these mollusks contain high amounts of zinc, which is essential for testosterone production and the maintenance of healthy sperm. Pair them with a glass of inhibition-lowering champagne to add even more fuel to the fire.

2. Watermelon

Recent research has shown that watermelon is rich with citrulline, an amino acid that helps improve blood flow to the heart, genitalia, as well as throughout the body. It does so by relaxing blood vessels, which is essentially what erectile dysfunction drugs do, too.

3. Asparagus

Although it's chock full of other valuable nutrients, the high folate content in asparagus is what earns this vegetable a spot on our list. Folate is one of the B vitamins, and among its many roles is increasing the production of histamine-an essential ingredient for orgasm in both sexes.

4. Dark Chocolate

As if you needed another reason to eat chocolate. Indulge in the antioxidant-rich dark variety to experience the release of two sexy chemicals: mood-boosting serotonin and phenylethylamine, a compound that mimics the brain chemistry of a person in love. No wonder a 2006 study published in the Journal of Sexual Medicine found that women who ate chocolate on a daily basis reported higher sexual function scores than those who did not.

5. Celery

Add a few stalks of celery to his salad, and you just might find your partner even more attractive than usual. Raw celery contains boosts the production of androsterone-an odorless hormone released through male perspiration, which can act as a pheromone to trigger female attraction.

6. Nuts, Seeds, and Other Monounsaturated Fats

According to Dr. Ann Kulze, author of Dr. Ann's 10-Step Diet: A Simple Plan for Permanent Weight Loss and Lifelong Vitality, monounsaturated fats-found in extra virgin olive oil, canola oil, nuts, seeds, and avocados-promote healthy blood flow through various mechanisms. And the better the blood flow, the better the sexual response.
