The effect that pineapple has on oral sex depends on how often you eat pineapple, the impact of other foods in your diet, your overall health, and other factors. In general, eating fruit causes bodily secretions to taste sweeter. Anecdotal evidence and a few small studies indicate that pineapple might have the biggest effect.

It's no surprise that what you eat affects the way you taste. After all, the feed given to animals affects the flavor of the meat. Therefore, it makes sense that what you eat affects how you taste, particularly your bodily secretions, including seminal and vaginal fluids.

There are a few studies on the topic and numerous blog posts sharing personal experiments. Two small studies include the pineapple sex test, conducted at porkandgin.com, and a review of online data from the Kinsey Institute. The limited data finds that male ejaculate and female vaginal secretions are affected by pineapple. It doesn't seem to matter whether the pineapple is fresh, canned, or juiced.

The effect isn't noticeable immediately after eating a few bites of pineapple. Most respondents saw a definite effect after eating pineapple for several days. The impact relates in part to the way ​food affects mucus production and composition. Chemicals in foods you eat are found in most secretions, including perspiration and breast milk as well as semen and vaginal fluid.

Key Takeaways: Pineapple and Oral Sex

  • The foods you eat affect the taste of bodily secretions, so they can have an effect on oral sex.
  • Research indicates eating pineapple may make secretions taste sweeter.
  • Other foods also influence body chemistry, including scent and flavor.


Foods That Might Make You Taste Sweeter (or Not)

In addition to pineapple, other foods reputedly change your body chemistry enough to alter the flavor of semen and vaginal fluid. These tend to be foods high in acidity or sugars and include:

  • Water
  • Liqueurs (but not so much alcohol as to cause dehydration)
  • Pineapple
  • Dried fruit
  • Fresh berries
  • Kiwi

Foods high in chlorophyll (wheat grass, celery, parsley) got mixed reviews. Several websites recommended them, but they didn't cite their sources, and none of the bloggers who tested them detected much effect. Another key factor is your hydration level. 

Just as some foods might make you taste better, others might have a negative impact, increasing bitterness. You and your partner might wish to limit:

  • Smoking
  • Coffee
  • Broccoli, cauliflower, asparagus, and other Brassica sp.
  • High levels of preservatives in foods
  • Certain drugs (specifics were not given)
  • Onions, garlic, and other Allium sp. (believed to be related to sulfur compounds)

There were mixed reviews concerning fish, red meat, dairy, and beer. Anecdotally, it would appear that eating meat is not a negative factor, as long as a person's diet regularly includes fresh fruits and vegetables.

Foods That Affect How You Perceive Flavor

Your perception of flavor relies on chemoreceptors. Compounds in the foods you eat not only affect your secretions and chemical composition but your ability to taste chemicals.

The enzyme bromelain in pineapples is a protease that literally dissolves proteins in your mouth, causing a prickly sensation and limiting your ability to perceive flavors.

The "miracle berry" (Synsepalum dulcificum) makes sour foods taste sweet. The berry contains a glycoprotein named miraculin that binds to receptors on taste buds. Sour foods are acidic, so they lower the pH inside the mouth. At low pH, miraculin activates sweet receptors. The effect lasts until saliva rinses away the protein, which takes about half an hour.

Sodium lauryl ether sulfate and sodium lauryl sulfate are surfactants in toothpaste that lower surface tension of fluid inside your mouth. This is great when you're brushing away bacteria, but the surfactants also wash away phospholipids that coat your tongue. The result explains why orange juice tastes vile if you drink it right after brushing your teeth. Incidentally, you'd get the same effect if you washed your mouth out with soap containing these common ingredients.

Artichoke, on the other hand, makes food taste sweeter. This results from a chemical reaction with the cynarine and chlorogenic acid in the plant. Cynarine inhibits your ability to taste sweet flavors, but the chemical is displaced by the next food you eat, automatically making it taste sweet.
