The intimate care aisle is one of those quiet corners of the internet where folklore travels faster than fact. Some of the things people repeat in articles and TikToks turn out to be wrong, and following them can actually make things worse. Here are the seven biggest myths, debunked clearly.
Myth one: spit works fine as lube
The most common DIY substitute is also one of the worst options. Saliva dries quickly, has a different pH than vaginal tissue, contains bacteria from your mouth, and provides almost no real reduction in friction beyond the first thirty seconds. It also breaks down some condom materials over time.
Spit is fine for the first ten seconds of anything. It is not a substitute for actual lubricant in any meaningful sense.
Myth two: coconut oil is the natural alternative
Coconut oil is genuinely smooth, and it feels gentle, and it is everywhere on wellness Instagram as the "natural" lube of choice. The problems: it breaks down latex condoms, it can disrupt the vaginal microbiome over repeated use, and it stains sheets in ways that are hard to wash out.
For occasional, condom-free use it is mostly fine. As a daily solution it usually creates more problems than it solves.
Myth three: if you need lube, something is wrong with you
Roughly half of women report needing additional lubrication during sex at least sometimes. The number goes up with age, with stress, with hormonal contraception, with antihistamines, with most antidepressants, during pregnancy, during menopause, and after childbirth. Using lube has nothing to do with attraction, arousal, or how a partner makes you feel.
It just means you are a human with a body that does not produce identical amounts of moisture in every situation. Which is to say, normal.
Myth four: more lube is always better
The right amount is the amount that reduces friction without flooding the area. Too much actually reduces sensation for both partners and can dilute condom lubricants, which makes them more likely to slip. A pea-sized to teaspoon-sized amount is plenty for most use cases. Add more only if you need it.
Myth five: silicone lube is the longest-lasting and therefore best
Silicone lasts longer because it does not absorb. That property is a benefit in water (it is the only lube that works in the shower or a bath) and in long sessions. But it ruins silicone toys, it is harder to clean up, and it can interfere with your body's own natural lubrication by coating the tissue.
For most situations, water-based is the better default. Silicone is a specialist tool for specific use cases.
Myth six: warming and tingling lubes are exciting
Most warming or tingling lubes work by including menthol, capsaicin, or other compounds that irritate the tissue. The sensation is mild irritation, repackaged as fun. For some people on some occasions, that lands. For most people most of the time, it triggers actual irritation and microbiome disruption.
If you have sensitive skin, are pregnant or postpartum, are perimenopausal or postmenopausal, or have had any recurrent infections, skip these entirely.
Myth seven: "doctor recommended" means anything
Any brand can put "doctor recommended" on a bottle. It is not a regulated claim. The few times it appears with an actual name and credentials attached, it usually means the brand paid a single doctor to endorse the product. It is marketing copy, not a quality indicator.
Trustworthy signals to look for instead: third-party ingredient testing, cosmetic registration in the EU (CPNP), pH and osmolality numbers published openly, ingredient list that is short enough to read.
The bonus myth: lube goes bad as soon as you open it
Most commercial lubes are designed to last 12 to 24 months after opening because of preservatives. The freshness loss is real but slower than people think. A bigger issue is exposure to heat and direct sunlight, which can degrade the formulation faster than the calendar.
If you mix your own from a powder, the dilution lasts about one to two weeks in the pouch at room temperature, then you mix a fresh one. No preservatives needed because you are not asking it to survive a year.
A formula that does not need the folklore
One ingredient, body-matched pH, no glycerin, no fragrance, no warming gimmicks. The straightforward formula you have been looking for.

Most lube myths come from the same place: the gap between what the industry sells and what your body actually needs. The fix is reading the label, ignoring the marketing, and choosing a formula simple enough that there is nothing to hide.
