Quick answer: Water-based lube is the most versatile, it's safe with all condom types and all sex toy materials, easy to clean up, and works for most situations. Silicone-based lube lasts longer and is ideal for shower or bath play, but shouldn't be used with silicone toys. Oil-based lube feels luxurious and is great for massage and external play, but it degrades latex condoms and isn't recommended for internal use with toys. For most people starting out, a good water-based lubricant is the right first choice.
Lube has a reputation problem. People think it means something's wrong, you're not wet enough, not turned on enough, not young enough. None of that is true. Lube is a tool, the same way a good pillow is a tool for sleep. You can technically sleep without one, but why would you? This is everything you need to know about choosing and using the right one.
Why lube matters (more than you think)
Natural lubrication varies. It varies by person, by day, by cycle stage, by stress level, by medication, by how much water you drank, by whether you rushed foreplay or took your time. It's not a reliable indicator of arousal and it's definitely not a measure of how attracted you are to someone. Plenty of people are mentally very into it while their body takes a different approach to the timeline.
Lube reduces friction. Less friction means less micro-tearing, less irritation, more comfort, and, here's the part that actually sells it, more sensation. Things slide the way they're supposed to. Vibrations transmit better against a lubricated surface. Penetration is smoother. External stimulation has less drag and more glide.
A 2013 study published in The Journal of Sexual Medicine found that lubricant use was associated with higher ratings of sexual pleasure and satisfaction for both solo and partnered sex. This wasn't a marginal difference. Participants consistently rated lubricated sex as more pleasurable, more comfortable, and more enjoyable overall.
The three main types of lube
We go deep on each of these in our water vs silicone vs oil lube comparison, but here's the overview.
Water-based lubricant
The all-rounder. Compatible with every condom material, every toy material, and every body. Cleans up with water. Won't stain your sheets. The downside: it absorbs into skin and evaporates, so you'll need to reapply during longer sessions. Some water-based lubes contain glycerin, which can contribute to yeast infections in people who are prone to them, check the ingredients if that's a concern.
Best for: everyday use, toy play, partnered sex with condoms, anyone who wants a simple no-drama option.
Silicone-based lubricant
The long-distance runner. Silicone lube doesn't absorb into skin or evaporate, so it stays slippery much longer than water-based. It's also waterproof, which makes it the only practical choice for shower, bath, or pool play. The catch: it can degrade silicone sex toys over time (more on that in our best lube for sex toys guide). It's also harder to wash off, soap and water needed, not just a quick rinse.
Best for: anal play, shower or water play, long sessions, people who hate reapplying.
Oil-based lubricant
The luxury option, with caveats. Oil-based lubes (coconut oil is the popular one) feel rich, last a long time, and double as massage oil. The problems: oil degrades latex and polyisoprene condoms, making them ineffective. It can also trap bacteria internally, increasing infection risk for vaginal use. And it will absolutely stain your sheets.
Best for: external massage, solo external play, partnered play when latex condoms aren't involved and both partners have been tested.
Choosing the right lube for the situation
With sex toys
Water-based is the safest default for toy play. Silicone lube and silicone toys don't mix, the lube can bond with the toy surface and cause it to degrade. We cover this in detail in the best lube for sex toys guide. If your toy is stainless steel or glass, you can use any lube type you like.
With condoms
Water-based and silicone-based lubes are both safe with latex, polyisoprene, and polyurethane condoms. Oil-based lubes (including coconut oil, vaseline, and most massage oils) will break down latex and polyisoprene within minutes. If you're using condoms for protection, keep oil-based lube away from them.
For anal play
The anus doesn't self-lubricate, full stop. Lube isn't optional here, it's essential. Thicker, longer-lasting formulas work best. Silicone-based lube is popular for anal play because it doesn't dry out. Water-based options work too, but you'll likely need to reapply. Avoid anything with numbing agents, pain is your body's feedback system, and you need it.
For solo play
Whatever feels best. Solo play is your lowest-stakes testing ground for trying different types. If you're using a vibrator, water-based is the safe bet (see our full lube and toy compatibility guide). If it's hands-only, try whichever type you're curious about.
In the shower or bath
Water washes away water-based lube almost immediately, which makes it useless for wet play. Silicone-based lube is the answer here, it's waterproof and stays slippery even under running water. Just be careful with silicone toys in this scenario (use a water-based lube with silicone toys even in the shower, and accept the reapplication).
Ingredients to watch out for
Not all lubes are created equal, and the ingredient list matters more than the branding.
-
Glycerin: A sugar alcohol that adds slipperiness. Can feed yeast, so if you're prone to yeast infections, go glycerin-free.
-
Parabens: Preservatives that mimic oestrogen. Research on health effects is mixed, but many people prefer to avoid them as a precaution.
-
Chlorhexidine: An antiseptic sometimes added to lubes. Can disrupt vaginal flora and cause irritation.
-
Nonoxynol-9: A spermicide that causes irritation and actually increases STI transmission risk with frequent use. Avoid in lubricants.
-
Propylene glycol: Can cause irritation in sensitive individuals. If you've ever had a burning reaction to a lube, this is a common culprit.
-
Warming or cooling agents: Menthol, capsaicin, or other sensation-enhancers. Fun for some, extremely irritating for others. Patch test before going all in.
How much lube to use
More than you think. Seriously. The most common mistake is using too little. Start with a coin-sized amount and add more as needed. You can always add more; you can't un-irritate tissue that got too much friction.
For anal play, use significantly more. The general rule is: if you think you've used enough, add some more. Reapply whenever things start feeling less smooth.
Lube myths that need to die
"If you need lube, something's wrong"
This is the big one and it's completely false. Needing lube means you're a human with a body that doesn't always produce the exact amount of moisture required for every sexual scenario. That's everyone. Medications (antidepressants, antihistamines, hormonal birth control), stress, dehydration, menopause, breastfeeding, dozens of factors affect natural lubrication that have nothing to do with arousal or attraction.
"Lube is only for older people"
The Indiana University study found lubricant use was common across all age groups, with the highest usage among 25-34 year olds. Lube is for anyone who wants sex to feel better. Age is irrelevant.
"You can use any household product as lube"
Vaseline, hand lotion, baby oil, cooking spray, people have tried all of these. Most are not formulated for contact with mucous membranes and can cause irritation, infections, or condom failure. Coconut oil is the one grey area (it's popular and generally well-tolerated externally), but it still degrades latex condoms. Use actual lubricant made for the purpose.
"More expensive lube is always better"
Not necessarily. Price often reflects packaging, branding, and marketing rather than formula quality. A well-formulated water-based lube with clean ingredients can cost under $15 and outperform a $40 bottle with a fancier label. Read the ingredient list, not the price tag.
Lube and your body
If you experience persistent irritation, burning, or discomfort with a lubricant, stop using it and try a different one. Vaginal and anal tissue are sensitive, and what works for one person may not work for another.
People with recurring infections (yeast or BV) should look for lubes that are pH-balanced for vaginal use (pH 3.8-4.5), glycerin-free, and paraben-free. The World Health Organisation recommends that personal lubricants have an osmolality below 1200 mOsm/kg to reduce tissue irritation. If you're experiencing ongoing issues, talk to your GP or sexual health provider, NHS Sexual Health Services can point you in the right direction if you're in the UK.
Storage and shelf life
Lubricant does expire. Check the date on the bottle. Most water-based lubes last 1-3 years unopened; silicone-based can last longer because the formula is more chemically stable. Once opened, use within a year. Store at room temperature away from direct sunlight.
If your lube has changed colour, consistency, or smell since you bought it, bin it. Expired or contaminated lube can harbour bacteria and irritate tissue.
Where to start
If this is your first time buying lube, start with a water-based formula. It's compatible with everything, easy to clean up, and low-risk. Use it with your toys, with a partner, or solo. Once you know you like using lube (you will), branch out and try silicone-based or explore our lube beginner's guide for a gentler introduction to the basics.

FAQs
Can lube cause a yeast infection?
Some ingredients can contribute to yeast overgrowth, glycerin is the main one. If you're prone to yeast infections, choose a glycerin-free, pH-balanced water-based lube. The lube itself isn't causing the infection, but certain ingredients can create conditions that make one more likely.
Is it safe to use lube every time?
Yes. There's no downside to using lube regularly. It reduces friction, which actually protects tissue from micro-tears and irritation. If anything, using lube consistently is better for your body than going without.
Can I use coconut oil as lube?
For external use, many people do and tolerate it well. For internal use, opinions are divided, it can disrupt vaginal pH and trap bacteria. It will definitely destroy latex condoms. If you're using condoms or are prone to infections, skip the coconut oil and use a purpose-made lubricant.
What's the difference between lubricant and massage oil?
Massage oils are formulated for external skin. They often contain fragrances, essential oils, and carrier oils that aren't suitable for mucous membranes or internal use. Lubricants are specifically formulated for genital contact and are pH-balanced accordingly. Don't swap one for the other.
How do I know which lube is right for me?
Start with water-based, it works with everything and has the fewest restrictions. From there, experiment based on the situation. Our water vs silicone vs oil comparison breaks down exactly when each type shines.
