Lube is the most underrated item in any toy collection. Most people buy it as an afterthought — a small bottle grabbed at checkout because it seemed sensible — and then use it interchangeably with every toy they own without giving it much further thought. This approach works, up to a point. But the wrong lube with the wrong toy doesn't just reduce the experience — it can permanently damage your toys, degrade their materials, and in some cases create a surface that harbours bacteria in a way that poses a genuine health risk.
Lube compatibility is not complicated once you understand the basic principles — but those principles matter, and most people don't know them. This guide covers every major lube type, every major toy material, and exactly which combinations work, which don't, and why.
If you're building your collection and want a broader view of what to prioritise at every budget, our blog How to Build a Sex Toy Collection on Any Budget is the ideal companion read to this one.
The Three Main Lube Types — A Quick Overview
Before getting into toy-specific compatibility, it helps to understand what the three main lube types actually are and what makes each one different.
Water-Based Lube
The most versatile lube type available. Water-based lubes are compatible with virtually every toy material and every type of condom. They're easy to clean up, gentle on body tissue, and widely available at every price point. The main limitation is longevity — water-based lubes dry out faster than silicone-based alternatives and require reapplication during longer sessions. For most people, most of the time, water-based lube is the right default choice.
Note on glycerin: Many water-based lubes contain glycerin — a sugar-based compound that keeps them slippery. Glycerin is generally safe but can trigger yeast infections or UTIs in people who are sensitive to it. If you notice recurring issues after lube use, switching to a glycerin-free formula often resolves the problem.
Silicone-Based Lube
Significantly longer-lasting than water-based lube — it doesn't dry out and maintains its slipperiness throughout a session without reapplication. Silicone lube is also the only lube type that remains effective in water, making it the correct choice for shower and bath play. It's condom-compatible and body-safe. The critical limitation: silicone-based lube degrades silicone toy surfaces. Never use silicone lube with silicone toys — the two materials react, causing the toy surface to become sticky, tacky, and permanently damaged.
Oil-Based Lube
Long-lasting, natural feeling, and excellent for massage and external play. Oil-based lubes — including coconut oil, natural massage oils, and oil-based commercial lubes — are not compatible with latex condoms, which they degrade rapidly. They're also harder to clean from both skin and toys, and they can increase the risk of bacterial vaginosis in some people. Oil-based lubes work well for manual play and for use with non-latex toys where condoms aren't involved, but are generally not the first recommendation for toy-specific use.
Hybrid Lube
A water base with a small silicone component — delivering longer-lasting performance than standard water-based lube while avoiding the full silicone content that causes toy degradation. Hybrid lubes are generally safe with silicone toys, but the silicone percentage varies between products. Always do a spot test on the base of a silicone toy before full use with any hybrid formula. Our blog What's Hybrid Lube and Why Do You Need It? covers this category in full detail.
Lube Compatibility by Toy Material
Silicone Toys
Silicone is the most popular sex toy material — and the one with the most important lube restriction. The rule is simple and non-negotiable: never use silicone-based lube with silicone toys. The two silicone compounds react at a molecular level, causing the surface of the toy to become permanently tacky, degraded, and porous — creating a surface that harbours bacteria and cannot be restored.
- ✓ Water-based lube — always safe, always compatible. The default choice for all silicone toys.
- ⚠ Hybrid lube — generally safe due to low silicone content, but do a spot test first. Apply a small amount to the base of the toy, rub for 30 seconds, and check for any tackiness or texture change before use.
- ✗ Silicone-based lube — never use with silicone toys. No exceptions.
- ✗ Oil-based lube — not recommended. Difficult to clean thoroughly from silicone surfaces and can degrade the material over time.
Toy examples: Most vibrators, rabbits, dildos, butt plugs, cock rings, and anal toys sold at Romantix. Browse our vibrators collection and dildos collection for silicone options.
Glass Toys
Glass is the most lube-permissive toy material available. Borosilicate glass is completely inert — it does not react with any lube type, does not degrade, does not become porous, and is compatible with water-based, silicone-based, oil-based, and hybrid lubes without any concern. The non-porous, ultra-smooth surface of glass means it requires less lube than most other materials to achieve the same level of slipperiness.
- ✓ Water-based lube — fully compatible.
- ✓ Silicone-based lube — fully compatible. A particularly good combination for longer sessions — the silicone lube's longevity works well with the smooth glass surface.
- ✓ Hybrid lube — fully compatible.
- ✓ Oil-based lube — compatible, though cleanup requires more attention than with water-based formulas.
Special note for water play: If using a glass toy in the bath or shower, use silicone-based lube — it's the only type that remains effective when diluted by water. Our blog Glass Sex Toys: Why They're Worth the Investment covers everything about this material category.
Stainless Steel Toys
Like glass, stainless steel is completely non-porous and inert — it does not react with any lube type. All four lube types are safe to use with stainless steel toys, making them as permissive as glass in terms of lube compatibility. Stainless steel surfaces are similarly smooth and require less lube volume than porous materials to achieve excellent slipperiness.
- ✓ Water-based lube — fully compatible.
- ✓ Silicone-based lube — fully compatible. Excellent combination for extended sessions.
- ✓ Hybrid lube — fully compatible.
- ✓ Oil-based lube — compatible with appropriate cleanup.
Toy examples: Steel butt plugs, steel anal beads, steel G-spot wands. Browse our butt plugs collection for steel options.
ABS Plastic Toys
ABS (acrylonitrile butadiene styrene) is a hard, rigid plastic commonly used for the external casing of vibrators, bullet vibes, and similar motorised toys. It's non-porous, body-safe, and durable. ABS plastic is compatible with water-based, silicone-based, and hybrid lubes without issue. Oil-based lubes are generally best avoided as they can be difficult to clean from the casing and may affect the finish over time.
- ✓ Water-based lube — fully compatible. Best default choice.
- ✓ Silicone-based lube — fully compatible with the ABS plastic itself. Note: many ABS plastic toys have silicone components (tips, heads, or inserts) — check the full material composition before using silicone lube.
- ✓ Hybrid lube — fully compatible with the ABS plastic component.
- ⚠ Oil-based lube — use with caution; can be difficult to clean thoroughly.
Toy examples: Hard-cased bullet vibrators, wand massager heads, some cock rings. Browse our vibrators collection for ABS plastic options.
TPE and TPR Toys
Thermoplastic elastomer (TPE) and thermoplastic rubber (TPR) are soft, flexible, skin-like materials used in many realistic dildos, masturbators, and affordable vibrators. They're porous materials — meaning bacteria can survive inside the material even after surface cleaning, which is why toys made from TPE and TPR should always be used with a condom. In terms of lube compatibility, both materials work well with water-based lube and are generally compatible with hybrid formulas. Silicone-based lube should be avoided as it can cause surface degradation in the same way it affects silicone toys.
- ✓ Water-based lube — fully compatible. The recommended choice for all TPE and TPR toys.
- ⚠ Hybrid lube — generally compatible but do a spot test first given the variable formulations.
- ✗ Silicone-based lube — avoid. Can cause surface degradation and tackiness.
- ⚠ Oil-based lube — not recommended. Difficult to clean from porous surfaces and can accelerate material degradation.
Toy examples: Realistic dildos, masturbators, some budget vibrators. Always use a condom with TPE and TPR toys for hygiene reasons regardless of lube choice. Browse our masturbators collection for TPE options.
Latex and Rubber Toys
Latex and rubber toys — less common in premium toy ranges but still present in some affordable products and BDSM accessories — have similar restrictions to latex condoms. Oil-based lubes degrade latex rapidly, causing it to break down and become unreliable as a barrier material. Water-based lube is the only fully safe choice for latex toys.
- ✓ Water-based lube — fully compatible. The only recommended choice.
- ✗ Oil-based lube — never use with latex. Causes rapid material degradation.
- ⚠ Silicone-based lube — not recommended. Can affect latex integrity over time.
- ⚠ Hybrid lube — use with caution due to silicone content.
Lube Compatibility for Specific Activities
Anal Play
Anal tissue doesn't self-lubricate — ever. The quantity of lube required for comfortable anal play is significantly more than for vaginal play, and the quality matters more because the rectal tissue is more vulnerable to friction-related micro-tears. For anal play with silicone toys, use water-based lube generously and reapply frequently. For anal play with glass or steel toys, a silicone-based lube is an excellent choice — its longevity significantly reduces the need for reapplication.
A thick, long-lasting formula is preferable to a thin, watery one for anal use — the cushioning effect matters. Browse our lubricants collection and look for formulas specifically marketed for anal use — these are typically thicker and longer-lasting than standard formulas.
Water Play — Shower, Bath and Pool
Water washes away natural lubrication and dilutes water-based lube almost immediately — which means that in the bath or shower, you're effectively playing without lube unless you use silicone-based formula. Silicone lube is the only type that remains effective when surrounded by water. If your waterproof toy is silicone, this creates the classic compatibility conflict — in which case use a water-based lube applied generously and accept that you'll need to reapply more frequently, or choose a glass or steel toy for water play and use silicone lube freely.
Using Condoms With Toys
When using a condom over a toy — for hygiene purposes, for use with porous toy materials, or for sharing between partners — always use water-based lube on the outside of the condom. Oil-based and silicone-based lubes both degrade latex condoms. Water-based lube is the only safe choice when a latex condom is in the equation, whether on a toy or a penis.
Temperature Play
For temperature play with glass or steel toys, any lube type works — but silicone lube holds up particularly well alongside the temperature experience because it doesn't change in texture or viscosity as the toy warms or cools. It also maintains the toy's slipperiness throughout the temperature transition in a way that water-based lube sometimes doesn't.

Common Lube Mistakes and How to Avoid Them
- Using silicone lube with silicone toys. The most common and most damaging lube mistake. The damage is permanent and irreversible. Always check the toy material before reaching for silicone lube.
- Using oil-based lube with latex condoms. Oil degrades latex rapidly and compromises the condom as a barrier. Always use water-based lube when latex condoms are involved.
- Not using enough lube. Under-lubrication is the most common mistake overall. More lube is almost always better — for comfort, for sensation, and for protecting toy surfaces from friction-related wear.
- Using the wrong formula for anal play. A thin, watery water-based lube is not adequate for anal play. Use a thicker formula and reapply more frequently than you think necessary.
- Using lube with body contact ingredients on sensitive tissue. Flavoured lubes, warming lubes, and cooling lubes often contain ingredients that aren't suitable for internal vaginal or anal use. Check the label — most will specify whether they're safe for internal use.
- Not cleaning lube off toys after use. All lube types — even the most compatible ones — should be cleaned off toy surfaces after every session. Lube left on toy surfaces over time can degrade even compatible materials, and silicone lube in particular can build up on surfaces and become difficult to remove if left for extended periods.
