For most people using condoms, water-based lube is the right choice. It works with every condom type - latex, polyisoprene, and polyurethane - and is safe with all sex toy materials. Silicone lube lasts longer, works in water, and is better for anal sex or longer sessions, but it cannot be used with silicone toys and costs more. If you are ever unsure, water-based is the safe default.
This guide explains both types in full, covers the compatibility rules that matter most when you are using condoms, and helps you decide which one to use for your situation.
What Is Water-Based Lube?
Water-based lubricant uses water as its primary ingredient, usually thickened with cellulose or a similar compound to improve staying power. It is the most widely used type of lube in the UK and the standard choice for use with condoms and sex toys.
The main advantage is compatibility. Water-based lube is safe with every condom material and every toy material. It washes off easily, does not stain, and rarely causes skin irritation. The trade-off is longevity - water-based lube can dry out during longer sessions, particularly in warm conditions, though adding a small amount of water or saliva instantly reactivates it.
What it is best for: everyday sex, use with condoms, use with silicone or rubber sex toys, people with sensitive skin.
What it is not ideal for: sex in water (showers, baths, pools) - water washes it away, making it ineffective. For water-based sex, use silicone lube instead.
Our pick: Durex Feel Lube
Neutral texture, no added fragrance, compatible with all condom types and toy materials. Available in 50ml and 100ml. The most straightforward choice if you want a reliable water-based lube that does exactly what it should.
Also recommended: Durex Naturals Pure Lube
A cleaner formulation using 97% natural-origin ingredients, free from parabens, colourants, and synthetic fragrances. pH-balanced and gynecologically tested. The right choice for sensitive skin or anyone who prefers a minimal-ingredient formula.
What Is Silicone Lube?
Silicone lubricant uses silicone polymers rather than water as its base. It does not absorb into the skin, does not evaporate, and is not washed away by water - which makes it significantly longer-lasting than water-based alternatives.
Silicone lube has a silkier, lighter feel than most water-based formulas. A small amount goes a long way. It is the best choice for anal sex (where you want maximum cushioning and longevity without stopping to reapply), sex in water, and longer sessions where reapplication is inconvenient.
The critical limitation: silicone lube degrades silicone sex toys. The lube bonds with the toy material and causes the surface to break down. If you use any silicone toys - vibrators, dildos, plugs - do not use silicone lube with them. Use water-based lube instead.
Silicone lube is safe with latex, polyisoprene, and polyurethane condoms.
Our pick: Uberlube Luxury Silicone Lubricant
A premium silicone lubricant with a very light, almost invisible texture - no residue, no stickiness. Fragrance-free, paraben-free, and enriched with vitamin E. Works in water and outside it. A small amount provides long-lasting coverage. Available in 55ml and 112ml with a pump dispenser.
Also recommended: ID Lube Millennium Pure Silicone Lubricant
High-quality pure silicone at a more accessible price than Uberlube. Unfragranced, extremely long-lasting, and a good choice if you want silicone performance without the premium price. Safe with all latex condoms.

The Condom Compatibility Rule
This is the most important section if you are using condoms. The rule is straightforward:
Both water-based and silicone lube are safe with latex and polyisoprene condoms.
The lube type that is never safe with latex or polyisoprene condoms is oil-based - that includes coconut oil, baby oil, petroleum jelly, body lotion, and any other oil-containing product. Oil degrades latex at a molecular level, making the condom significantly more likely to split during use. This affects both contraceptive protection and STI prevention.
| Lube Type | Latex Condoms | Polyisoprene Condoms | Polyurethane Condoms |
|---|---|---|---|
| Water-based | Safe | Safe | Safe |
| Silicone | Safe | Safe | Safe |
| Oil-based | Not safe | Not safe | Safe |
Polyurethane condoms - such as non-latex alternatives - are oil-resistant, but water-based or silicone is still the practical recommendation for everyday use.
Using lube with a condom is actively beneficial: it reduces friction, which lowers the chance of the condom breaking. The key is using the right type.
Toy Compatibility
The rule here is simpler but equally important:
Water-based lube is safe with all toy materials - silicone, rubber, TPE, glass, metal, and hard plastic.
Silicone lube is not safe with silicone toys - it bonds with the surface and causes degradation over time. If you are unsure what material your toy is made from, use water-based lube to be certain.
If you want to use silicone lube during anal play but also use silicone toys, a hybrid lube is the practical middle ground (see below).
What About Hybrid Lube?
Hybrid lubricants blend silicone and water-based ingredients. They last longer than pure water-based but are generally safer with toys than pure silicone - though not universally so. Check the product label before use with silicone toys.
Hybrid lube is particularly useful for anal sex if you also use toys, since it provides the cushioning and longevity of silicone without the same material compatibility risk.
Recommended: Skins Anal Hybrid Silicone and Water-Based Lube
A thicker-than-standard formula designed for anal use. Longer-lasting than water-based, compatible with latex condoms, and generally safe with most toy materials. One of the best-value anal lubricants in the UK.
Which Should You Use? Quick Guide
Use water-based lube if:
- You use latex or polyisoprene condoms and are not sure which lube to buy
- You use silicone sex toys
- You have sensitive skin
- You want something easy to clean up
Use silicone lube if:
- You are having sex in water
- You want maximum longevity without reapplying
- You are having anal sex and do not use silicone toys
- You are using polyurethane (non-latex) condoms
Use hybrid lube if:
- You want silicone-level longevity for anal sex but also use toys
Frequently Asked Questions
Can you mix water-based and silicone lube together?
You can, but there is no practical reason to. They do not blend well and the result is uneven in texture. If you want longer-lasting coverage than water-based provides, switch to silicone or hybrid rather than mixing.
Which lube is best for anal sex?
Silicone or hybrid lube. Anal tissue does not self-lubricate and requires more coverage for longer than vaginal tissue. Silicone lasts the longest and provides excellent cushioning. If you use silicone toys, use a hybrid instead. For a full breakdown see: Best lube for anal sex.
Does lube expire?
Yes - all lubricants have a shelf life, typically two to five years from manufacture. Check the PAO (period after opening) symbol - it looks like an open jar with a number inside, such as 12M. Using lube past that date is not recommended. Full breakdown: Does lube expire?
Is silicone lube safe during pregnancy?
Silicone lube is generally considered safe for use during pregnancy, but if you have any concerns speak to your midwife or GP. Water-based lube with a minimal ingredient list - such as Durex Naturals Pure - is often the recommended option during pregnancy due to its clean formulation.
Which lube lasts longer?
Silicone lasts significantly longer. It does not absorb into skin or evaporate, so one application typically covers an entire session without needing to reapply. Water-based lube can dry out during longer sessions, though it reactivates instantly with a small amount of water.
