The three main types of lube are water-based, silicone-based, and oil-based. Water-based lube is compatible with all condoms and all sex toys. Silicone-based lasts longer but will degrade silicone toys. Oil-based lube is not safe to use with latex condoms - it breaks down the material and can cause condom failure. Getting this compatibility right matters, because choosing the wrong lube with a latex condom is one of the most common reasons condoms break.
Beyond these three, there are hybrid lubes, anal-specific formulas, warming lubes, and flavoured options - each with their own rules. This guide covers all of them.

Why lube matters
Lube is not just for people who experience vaginal dryness. It makes sex more comfortable for everyone, reduces friction that can cause condoms to break, and is essential for anal sex, which produces no natural lubrication at all.
Friction during sex causes micro-abrasions in vaginal and anal tissue. These tiny tears are not just painful - they increase the risk of STI transmission by creating entry points for viruses and bacteria. Using lube reduces that friction and lowers the risk of both condom failure and tissue damage.
Studies show that using a water-based lubricant significantly reduces condom breakage rates. The WHO recommends lubricants with a pH compatible with the vagina (around 4.5) and an osmolality below 1200 mOsm/kg. Most standard water-based lubes meet both criteria.
Water-based lube
Water-based lube is the most versatile option and the safest starting point for most people. It works with every type of condom - latex, polyisoprene, and polyurethane - and is safe with all sex toy materials, including silicone.
What it's good for: Vaginal sex, oral sex, masturbation, sex toys. Works in almost any situation.
Pros:
- Safe with all condom types
- Safe with all toy materials
- Easy to wash off - no staining
- Least likely to cause irritation
- Good for people with sensitive skin or allergies
Cons:
- Dries out faster than silicone or oil-based lubes
- Needs reapplication during longer sessions
- Not suitable for use in water - it washes off
Best for: Anyone using latex condoms, anyone using silicone toys, and anyone new to using lube.

Silicone-based lube
Silicone-based lube lasts significantly longer than water-based. It doesn't dry out, it doesn't wash off in water, and it requires less frequent reapplication. It's a popular choice for anal sex and for people who experience vaginal dryness, because the slicker consistency holds up over time.
What it's good for: Longer sessions, anal sex, water play (showers, baths), and anyone who finds water-based lube dries out too quickly.
Pros:
- Long-lasting - no need to keep reapplying
- Safe with all condom types (latex, polyisoprene, polyurethane)
- Works in water
- Hypoallergenic - good for sensitive skin
- Ideal for anal play and vaginal dryness
Cons:
- Not safe with silicone sex toys - it causes the toy's surface to degrade and become porous, which can harbour bacteria
- Harder to wash off - requires soap and water
- Can stain sheets and fabrics
The critical rule: If your toy is made from silicone (the most common toy material), do not use silicone-based lube with it. Use water-based instead. If you are not sure what your toy is made from, default to water-based.

Oil-based lube
Oil-based lubes are long-lasting and moisturising. Natural oil-based options like coconut oil are popular for skin-to-skin massage and partnered play without a condom. But there is one non-negotiable rule: oil-based lube cannot be used with latex condoms.
Oil degrades latex. Even a small amount will weaken the material and significantly increase the chance of the condom tearing during sex. This applies to coconut oil, olive oil, petroleum jelly, baby oil, and any commercial oil-based lube.
What it's good for: Massage, sex without latex condoms (with polyurethane or nitrile condoms, or when not using a condom at all), extended skin-to-skin contact.
Pros:
- Very long-lasting
- Moisturising for skin
- Natural options available (coconut oil, aloe vera)
- Good for massage
Cons:
- Not safe with latex condoms - will cause failure
- Can increase risk of vaginal yeast infections (thrush)
- Difficult to wash out - can stain sheets and clothing
- May clog pores with regular use
The critical rule: Never use oil-based lube with a latex condom. If you are using condoms for contraception or STI protection, choose water-based or silicone-based instead.
Hybrid lube
Hybrid lubes combine water-based and silicone-based ingredients, giving you a longer-lasting formula that is still easy to clean up. They're a good middle ground for people who want more staying power than a water-based lube but find pure silicone lubes too slick or hard to remove.
Pros:
- Longer-lasting than water-based
- Easier to clean than silicone-based
- Safe with condoms
- Safe with most sex toys - check the label, as some hybrids still contain enough silicone to affect silicone toys
Cons:
- May still affect silicone toys depending on silicone content
- May need reapplication more often than pure silicone
Anal lube
The anus produces no natural lubrication. This makes a good quality anal lube essential for safe, comfortable anal sex - not optional. Using insufficient lube for anal play risks tearing delicate tissue, which increases the risk of STI transmission and causes pain.
Anal lubes are typically thicker than standard lubes. A higher viscosity formula clings to tissue and provides a longer-lasting cushion under pressure. Look for formulas specifically designed for anal use.
What to look for:
- Thicker consistency than standard vaginal lube
- Safe with latex condoms (if using condoms)
- pH compatible - the anal canal has a more neutral pH (around 5.5-7)
Avoid anal numbing lubes. Products that contain benzocaine or lidocaine temporarily reduce sensation, which can mask pain that signals you to slow down or stop. Pain during anal sex is protective information. Numbing it increases the risk of injury.

Warming and tingling lube
Warming and tingling lubes use ingredients like glycerol or L-arginine to create a warming or buzzing sensation. They can enhance pleasure but come with some important caveats.
High concentrations of glycerol - which is what typically creates the warming effect - can have a drying effect on vaginal and anal tissue. This counteracts what lube is supposed to do. Some warming lubes are better formulated than others, so check the ingredients.
If you experience any burning, stinging, or discomfort with a warming or tingling lube, wash it off immediately. Start with a small amount applied externally first to test your sensitivity before using it internally.
Flavoured lube
Flavoured lubes are designed for oral sex. They make licking and tasting more enjoyable and can be a fun addition to foreplay.
The important thing to know: flavoured lubes are generally not suitable for internal vaginal use. Most contain flavouring agents - sometimes including sugar compounds - that disrupt vaginal pH and can trigger yeast infections or bacterial vaginosis. If the packaging does not explicitly state it is safe for vaginal use, keep it external.
Flavoured lube is perfectly safe for oral sex on the penis, clitoris, or anus. It should not be used as a standard vaginal lubricant during penetrative sex.
For more detail on this, see our guide: is flavoured lube edible? A guide to flavoured lubricants.
Browse flavoured condoms if you want taste without the lube.
Natural and organic lube
Natural and organic lubes are made without parabens, synthetic fragrances, or harsh chemicals. They are popular with people who have sensitive skin, allergies, or who prefer products with cleaner ingredient lists.
Pros:
- Free from parabens and synthetic additives
- Good for people with sensitivities
- Often vegan-friendly
- Generally lower risk of irritation
Cons:
- Can be more expensive
- Natural doesn't automatically mean safe with latex condoms - check the base (water, oil, or silicone)
If you are trying to conceive, look specifically for a fertility-friendly lube. Many standard lubes contain ingredients that can impair sperm motility. Avoid lubes with petroleum, parabens, propylene glycol, glycerol, or Non-oxynol-9 if you are trying to get pregnant.
Ingredients to avoid
These ingredients appear in some commercial lubes and are worth avoiding:
- Glycerin - can feed yeast in the vagina and contribute to infections
- Parabens - associated with vaginal irritation; thought to be endocrine disruptors
- Chlorhexidine gluconate - kills lactobacilli, the healthy bacteria that protect vaginal pH
- Nonoxynol-9 - a spermicide that can irritate vaginal and anal tissue and may increase STI risk with frequent use
- Petroleum/petroleum jelly - degrades latex condoms and difficult to remove from vaginal tissue
- Propylene glycol - can cause irritation in sensitive users
- Undisclosed fragrances or flavourings - potential allergens; avoid unless clearly listed
pH and vaginal health
Healthy vaginal pH sits between 3.8 and 4.5. Lubes that fall outside this range can disrupt the natural bacterial balance, reducing lactobacilli and opening the door to infections like bacterial vaginosis or thrush.
The WHO recommends lubes with a pH of around 4.5 and an osmolality below 1200 mOsm/kg. Most well-made water-based lubes meet this standard. If you have recurring vaginal infections, checking the pH of your lube is a sensible starting point.
The anal canal has a more neutral pH (around 5.5-7), so pH matching is less critical for anal-only use.
Warming lubes, flavoured lubes, and some natural lubes can fall outside the recommended pH range. If vaginal health is a concern, stick to pH-balanced, unflavoured, water-based lube for internal use.
See our guide on lube expiry - old lube can change in composition and cause unexpected reactions.
How to choose the right lube
The compatibility rules are the starting point:
| Lube type | Latex condoms | Silicone toys | Best use |
|---|---|---|---|
| Water-based | Safe | Safe | Versatile - works for everything |
| Silicone-based | Safe | Not safe | Anal sex, longer sessions, water play |
| Oil-based | Not safe | Safe | No-condom play, massage |
| Hybrid | Safe | Check label | Middle ground option |
Beyond compatibility, think about:
- Duration - will you need to reapply? Water-based may need top-ups; silicone will not.
- Sensitivity - if you have had reactions before, look for paraben-free, glycerin-free, unflavoured options.
- Activity - anal sex needs a thicker formula; oral play works well with flavoured; everyday vaginal use does best with pH-balanced water-based.
- Condoms - if you are using latex condoms, water-based is the safest and simplest choice.
A few practical tips: start with a small amount and add more as needed; apply to both partners or the toy before use; store in a cool, dry place away from direct sunlight; check the expiry date before use; test a small amount on non-genital skin first if you suspect sensitivities.
