Your diet greatly affects every single piece of your body. You are literally what you eat (and drink!). This includes your bodily secretions! If you have an unhealthy diet, you are more likely to naturally stink and taste bad. Even some extremely healthy food can make you reek because of the pungent chemicals in them. Have you ever eaten a lot of garlic or onion and then tasted it hours or even a day later? That's because of those pungent chemicals getting into your system during and after digestion. It also affects the taste of your sexual bodily secretions, in all sexes! So you've got this date with a real cutie tomorrow and you're pretty sure things are going to happen after bar-hopping, what can you do to make sure your "secretions" don't taste like clam juice and garlic?
One thing to remember is that your body takes time to process what you put into it, so eating some oranges right before your date probably isn't going to help you. It's what you ate the day before (or as soon as 12 hours before) that affects it.
It's also pretty easy to tell someone's overall health by the taste of their cum. Someone in good health with a balanced diet should taste lightly salty and be slightly off white in color. Females should have a light taste. Strong, yeasty, salty smells often mean infection and/or a bad diet. In females, bodily fluid color can vary depending on the time of the month, but it should be either clear or a little cloudy. Someone who eats lots of meat, cheese, junk food, and booze is going to smell and taste like sewage and even be yellowish in color. Yellowish semen can also mean that the person hasn't released in a week or more, especially if the cum is in thick globs instead of a smooth sticky stream. It can also mean that they have an infection! If you didn't already know this, it's quite unhealthy to not masturbate regularly! Masturbating and not ejaculating can also make your cum taste pretty horrible. For the best tasting cum (in all sexes) make sure to release often!
Here are some food and drinks that greatly affect your fluid's taste:
Alcohol and coffee:
Drinking a couple of double tall lattes before work and having some shots with buddies in the evening is going to make you taste pretty nasty the next day. Caffeine and alcohol are definitely things to avoid.
Asparagus, onions, garlic:
As wonderful as these veggies are for you, they contain chemicals that make your body's fluids smell and taste rather awful. Make sure to eat these often, but not the day before you plan on getting laid.
You know what this is, I hope. It's the chemical that makes plants green, and it's incredibly good for your body. It also helps your bodily fluids taste better! Veggies like collard greens, kale, celery, parsley and other green leafy vegetables should be a regular part of your diet anyways, but make sure to eat extra if you're trying for tasty sexy fluids.
Meat and dairy:
It's (usually) true that vegetarians usually have better tasting cum. They tend to be more aware of their diets and eat more balanced meals in order to get the vitamins and minerals they're not getting from meat. Meat and dairy play a big role in your bodily fluid's flavor. Be sure to order a salad instead of that steak and cheese quesadilla the night before your date.
Pineapples are famously known for making your bodily fluids tasty and sweet, but other acidic fruits help too! Mangoes, oranges, lemons and other acidic fruits are great choices. Juice also counts. Smoothies are a great idea. You can throw some kale and other greens in those too.
Toxins and water:
Any toxins that your body is filtering out go out through your bodily fluids. Synthetic drugs (including prescription medications) and cigarettes contain lots of toxins that will make your cum taste really awful. Drinking plenty of water helps your body filter out nasty toxins, so keep hydrated and avoid drugs before your date. Even some natural drugs like marijuana have been said to influence the taste of your cum, but some people really like the taste of weed so that may be a good thing.
Certain spices like mint, peppermint, cardamom and cinnamon are well known for making your fluids taste better. Try a few cups of herbal tea with lemon and honey.
Salads, fruit smoothies and fresh veggies are great ways to make you taste (and smell, and feel) better, just keep an overall balanced diet, low in junk food, caffeine and alcohol. It's true that healthier people have better sex for multiple reasons, one of them being tastier cum!
