Lubricant is the cheapest upgrade in this entire category and the one people are least likely to buy. It costs about €15, it fixes the single most common complaint anyone has about comfort, and it still gets treated as an admission of failure rather than as equipment. So: how to choose a lubricant, what the three types actually do, and which combinations quietly ruin things.
What it's for, since this is where the confusion starts
Lubricant reduces friction. That's the whole job. It is not a correction, a substitute, or a verdict on arousal — natural lubrication varies with hydration, stress, sleep, medication, hormonal contraception and where you are in your cycle, and it correlates only loosely with how interested you are.
Friction is also the reason a perfectly good product gets described as uncomfortable. Silicone against skin has drag. Remove the drag and most of the complaint disappears.
The three bases, honestly compared
Water-based
The default, and the right answer for most people. Compatible with every material and every condom, easy to wash out of fabric, no residue. The trade-off is that it absorbs and evaporates, so it needs reapplying — which is a minor irritation, not a flaw. A splash of water often reactivates it rather than requiring more product.
Choose it if: you own silicone toys, you want one bottle that does everything, or you don't want to think about this again.
Silicone-based
Lasts far longer, stays slippery in water, and needs much less product per use. Excellent for showers and for anything long. Two catches: it can degrade the surface of silicone toys over time, and it needs soap to wash off skin and fabric.
Choose it if: you want longevity, you're using it in water, or your toys are glass or stainless steel rather than silicone.
Oil-based
Long-lasting and pleasant for massage. It also destroys latex condoms, is harder to clean, and stains. Massage oil is a lovely thing to own; it simply isn't the same product as lubricant, and it shouldn't be used as one if condoms are involved.
Choose it if: you're giving a massage. That's genuinely the use case.
The compatibility rules worth memorising
- Silicone toy + water-based lubricant. The safe default. If everything else falls out of your head, keep this one.
- Silicone toy + silicone lubricant. Avoid, or patch-test on the base of the toy first and check for tackiness after an hour.
- Glass or stainless steel + anything. Non-reactive. Silicone lubricant is often the better pairing here.
- Latex condoms + oil. Never. Oil weakens latex quickly enough to matter.
- Latex condoms + water or silicone. Both fine.
- Hybrid lubricants (water base with a little dimethicone) sit in between — usually fine with silicone, still worth a patch test.
The ingredients list, briefly
Most lubricants are unremarkable. A few things are worth a glance before you buy.
Glycerin and propylene glycol
Both are common humectants and both are fine for plenty of people. If you're prone to thrush or irritation, they're the easiest variable to remove — switch to a glycerin-free formula for a month and see whether anything changes. Evidence on this is mixed; personal pattern is more useful than the general claim.
Warming, tingling and flavoured
These work by irritating tissue slightly, which is exactly as appealing as it sounds once you know. They're not dangerous, but they're a novelty rather than an upgrade, and they're a poor first purchase.
Osmolality and pH
Two words that sound technical and are actually practical. Osmolality is how concentrated the formula is relative to your tissue; very high figures draw moisture out of cells, which can leave things drier and more irritated afterwards. WHO guidance suggests staying at or below around 380 mOsm/kg where possible, and treats products above 1,200 as best avoided. pH matters because vaginal tissue sits at roughly 3.8–4.5 and rectal tissue closer to neutral — a lubricant near the relevant range is gentler than one far outside it.
Good manufacturers publish both figures. Not publishing them isn't proof of a bad product, but publishing them is a reasonable sign of a serious one.
Most people use too little
A pea-sized amount is a demonstration, not a dose. Start with more than feels sensible, apply it to both the product and the body rather than only one, and reapply before things start feeling dry rather than after. Warming it briefly between your hands removes the small shock of something cold, which is the most common reason a first attempt goes badly.
For internal use and anything involving a plug, a thicker gel-textured lubricant stays where you put it. Thin, runny formulas are better for external use and for anything that needs to feel barely present. Our guide to plugs goes into that distinction in more detail.
When dryness is the pattern rather than the exception
Lubricant solves friction in the moment. It does not address persistent dryness, which is common and has ordinary causes — hormonal contraception, antidepressants, antihistamines, breastfeeding, perimenopause, or simply a stressful few months.
If discomfort is consistent rather than occasional, or if it comes with pain, that's worth raising with a doctor. A vaginal moisturiser used regularly does a different job from a lubricant used situationally, and the distinction is one a pharmacist can explain in about a minute.
Common questions
Can I use coconut oil?
It works as a lubricant and it destroys latex condoms. It's also harder to clean up than people expect. If condoms aren't involved it's not dangerous, but a purpose-made product is a better tool for about €15.
Does lubricant expire?
Yes — most formulas carry a shelf life of two to three years unopened, and a period-after-opening symbol on the label. Separation, a change in smell, or a change in texture means bin it.
Is silicone lubricant really bad for silicone toys?
Not instantly, and not always. The risk is gradual surface degradation, which shows up as tackiness or a dulled finish. Since water-based works perfectly well with silicone, there's little reason to take the chance.
How much should I spend?
Around €15 buys a good one. Above that you're mostly paying for packaging, and below it you're often paying for glycerin and filler.
One bottle or two?
One water-based bottle covers almost everything. A second silicone bottle makes sense if you use toys in the shower or want fewer reapplications — and if your toys aren't silicone.
