Lube comes up constantly across this site — in position guides, toy reviews, anal prep — but it's never gotten its own explainer, and it should. Getting the type wrong isn't just a minor inconvenience: the wrong lube can degrade a condom, ruin a toy, or just stop working halfway through. Here's what actually matters.
| Type | Best for | Avoid with | Cleanup |
|---|---|---|---|
| Water-based | Everything — the safe default | Nothing specific; reapply more often | Easy, water rinses it off |
| Silicone-based | Longer sessions, shower or bath use | Silicone toys — degrades the material | Needs soap, doesn't rinse with water alone |
| Oil-based | External massage, non-condom use | Latex condoms — breaks them down | Needs soap; can stain fabric |
Water-based: the default for a reason
Water-based lube is compatible with every condom material, every toy material, and washes off with water alone. The tradeoff is that it dries out faster than the alternatives, especially during longer sessions, so reapplying is normal and not a sign anything's wrong. If you only ever buy one type, this is it.
Silicone-based: lasts longer, one real restriction
Silicone lube stays slick far longer than water-based, which makes it a common pick for shower or bath use since water alone won't wash it away mid-session. The one rule that matters: don't use it with silicone toys. Silicone-on-silicone contact degrades the toy's surface over time, making it stickier and harder to clean — a genuinely common way people damage otherwise good toys. If you're using silicone lube, stick to glass, stainless steel, or ABS plastic toys, or your own bare skin.
Oil-based: fine for some uses, risky with condoms
Oil-based lubricants (including things like coconut oil, sometimes recommended informally) feel nice for external massage but break down latex condoms within minutes of contact, which can cause them to fail silently. If condoms are part of your protection plan, oil-based lube is a hard no for anything condoms will touch. It's also harder to wash off and can stain sheets or fabric.
What to check on the label
- Glycerin and parabens: some people are sensitive to these common lube ingredients — if a lube has caused irritation before, look for a glycerin-free or paraben-free formula.
- Osmolality (if listed): lubes with very high osmolality can irritate sensitive tissue with repeated use; it's a minor consideration for most people but worth knowing if irritation is a recurring issue.
- "Warming" or "tingling" formulas: these contain added ingredients that can be irritating for some people — worth testing on a small area first if you're new to a specific product.
How much is actually enough
More than feels necessary at first. Running low mid-session is one of the most common causes of unexpected discomfort, especially for anal sex, where the body doesn't self-lubricate at all — see our anal sex prep guide for more on that specifically. Reapplying isn't a sign something's wrong; it's just normal maintenance.
