Your body’s natural scent and taste down there are shaped by a handful of controllable factors: how you wash, what you eat, what you wear, and the balance of bacteria living on and around your genitals. Most of the time, a mild scent is completely normal. The goal isn’t to eliminate it but to keep things balanced so nothing unpleasant takes over.
What “Normal” Actually Smells Like
Healthy genitals have a scent. For people with vaginas, a slightly tangy or musky smell comes from the same bacteria that keep the area healthy. The vagina maintains a naturally acidic environment, with a pH between 3.8 and 4.2, thanks to beneficial bacteria that produce lactic acid and hydrogen peroxide. That acidity is what prevents harmful microbes from gaining a foothold, and it gives vaginal fluid its characteristic mild taste.
The scent also shifts throughout the menstrual cycle. Research on vaginal odor across cycle phases found that secretions around ovulation tend to be milder and more neutral, while those during menstruation and the luteal phase (the stretch after ovulation) are slightly stronger. This is hormonal and completely expected. Similarly, for people with penises, a light musk from sweat and skin oils in the groin is normal. Problems start only when bacteria or yeast are allowed to accumulate unchecked.
How to Wash Without Making Things Worse
One of the most common mistakes is overwashing or using the wrong products. Regular soap, shower gel, bubble bath, and anything with fragrance can disrupt the delicate skin and microbial balance of the genital area. The Royal College of Obstetricians and Gynaecologists specifically advises against using soap, scrubs, deodorants, or douches on the vulva. Clinical guidelines recommend a pH-balanced, hypoallergenic liquid wash (in the pH 4.2 to 5.6 range) for daily vulvar cleansing. Interestingly, washing with plain water alone isn’t ideal either. It can dry out the skin and worsen itching, which raises infection risk.
For people with penises, mild fragrance-free soap and water work well. If you’re uncircumcised, gently pull the foreskin back as far as it comfortably goes and clean underneath with a soft cloth or your hands. Smegma, the whitish buildup of dead skin cells and oils under the foreskin, is one of the most common causes of a strong odor. Washing regularly prevents it from accumulating. After washing, dry the area thoroughly before putting on underwear. Moisture left behind feeds the bacteria that cause odor.
The inside of the vagina is self-cleaning. Never douche or insert soap, cleansers, or “detox” products. These strip away protective bacteria and raise the pH, creating the exact conditions that lead to infections and bad smells.
What You Eat Changes How You Taste
Diet genuinely affects the flavor and smell of genital secretions, but not in the way most people think. You’ve probably heard that eating pineapple makes you taste sweeter. There’s a kernel of truth to it: foods with high water content and natural sugars can make secretions milder. But a single pre-sex snack won’t do much. What matters is your overall dietary pattern over days and weeks.
Pungent foods like garlic, onions, asparagus, red meat, and strong cheeses tend to produce a more intense smell and taste. Alcohol and cigarettes are linked to a bitter flavor. On the other hand, staying well hydrated and eating fruits, vegetables, and whole grains with high water content tends to keep things more neutral. Hydration is probably the single simplest lever you can pull. When you’re dehydrated, all your secretions become more concentrated and stronger in taste.
Choose Breathable Fabrics
The underwear you choose has a surprisingly large effect. Cotton is the gold standard because it wicks away sweat and moisture, depriving odor-causing bacteria and yeast of the damp environment they need to multiply. Synthetic fabrics like nylon and polyester trap heat and moisture against the skin, which accelerates bacterial growth.
If you prefer the look or fit of synthetic underwear, you might assume a cotton crotch panel solves the problem. It doesn’t fully protect you. That small panel can’t breathe the way 100% cotton does. For the best results, stick with all-cotton underwear, especially during warmer months or on active days. Sleeping without underwear or in loose-fitting shorts also gives the area a chance to air out overnight.
When Odor Signals Something Medical
A persistent fishy smell, especially accompanied by a thin grayish or yellowish discharge, is the hallmark of bacterial vaginosis (BV). BV happens when the normal balance of vaginal bacteria tips in favor of harmful species, pushing the pH above 4.5. It’s the most common vaginal infection in people of reproductive age and is treatable with a short course of antibiotics.
A yeasty or bread-like smell paired with thick white discharge and itching usually points to a yeast infection. Strong, foul odors that come on suddenly or that smell distinctly different from your normal scent are worth getting checked. For people with penises, a persistent smell despite good hygiene could indicate a yeast infection under the foreskin or a bacterial skin infection.
Probiotics for Microbial Balance
Because vaginal health depends so heavily on beneficial bacteria, there’s growing interest in using probiotics to support it. Clinical evidence points to a few specific strains that actually work. Lactobacillus rhamnosus GR-1 and Lactobacillus reuteri RC-14 are the most studied. In one trial, healthy women who took daily oral capsules of these strains for 60 days saw a significant improvement in vaginal microflora: 37% achieved normal bacterial colonization compared to just 13% on placebo.
These probiotics help by repopulating the vagina with acid-producing bacteria, which lowers pH and crowds out the species responsible for off-putting odors. A typical dosage used in clinical trials is one to two capsules daily containing around 10 billion CFUs each, taken for four to eight weeks. You can find supplements containing these strains at most pharmacies. They’re not a replacement for treating an active infection, but they can help maintain balance after treatment or as ongoing support if you’re prone to BV or yeast infections.
Daily Habits That Make a Difference
Beyond washing and diet, a few practical routines help keep things fresh. Change out of sweaty workout clothes and wet swimsuits as soon as possible. Bacteria multiply fast in warm, moist fabric pressed against skin. If you use panty liners, swap them out every few hours rather than wearing the same one all day.
Trimming or grooming pubic hair is a personal choice, but hair does trap sweat and bacteria close to the skin, which can intensify odor. You don’t need to remove it entirely. Even keeping it shorter reduces moisture retention. After sex, a quick rinse of the external area helps wash away the mix of fluids, sweat, and bacteria that can produce a stronger smell if left to sit.
For people with penises, the same logic applies. Wash after exercise, after sex, and at least once daily. Dry thoroughly, wear breathable fabrics, and keep the area ventilated when you can. Good hydration, a balanced diet, and basic consistent hygiene do more for how you smell and taste than any specialty product on the market.
