Personal lubricant — commonly called lube — is a liquid or gel specifically formulated for use during sexual activity to reduce friction between body parts or between a body and a sex toy. It is one of the most widely recommended sexual health tools available.Personal lubricant is recognised by the World Health Organization as a legitimate self-care sexual health intervention and is widely used across all ages, genders and sexual orientations. Its reputation as a niche product for specific problems understates how broadly it benefits people across all circumstances.
What Personal Lubricant Does
Friction during penetrative sex, masturbation or toy use causes discomfort, irritation and — without adequate lubrication — micro-tears in vaginal and anal tissue. These micro-tears are not only painful; they create entry points for pathogens and increase STI susceptibility. Personal lubricant creates a slippery layer that eliminates this friction, making sex more comfortable and in many ways safer.
Beyond preventing harm, personal lubricant actively enhances pleasure. By removing friction-related irritation, it allows sensation from touch, pressure and vibration to be felt more clearly. Many people who have always had sufficient natural lubrication find their experience meaningfully improved by adding lubricant.

Water-Based: Start HereThe universal default. Safe with every condom type and every toy material. Feels closest to natural lubrication. Easy to clean. The right choice for most people most of the time.
Silicone-Based: Longer SessionsLasts significantly longer without reapplication. Condom-safe and water-resistant. Ideal for anal sex or longer sessions. Cannot be used with silicone toys.
WHO RecognitionThe World Health Organization lists personal lubricant as a self-care intervention for sexual functioning and well-being — a recognition of its genuine health value beyond pleasure enhancement.
Improves Condom ReliabilityApplied to the outside of a condom, water-based or silicone-based lube reduces friction-caused breakage. Lube makes condoms more effective, not less.
For Vaginal DrynessImmediately effective for vaginal dryness from any cause — hormonal changes, medication, stress, breastfeeding or menopause. Available without prescription.
Essential for Anal SexThe anus produces no natural lubrication. Personal lubricant is not optional for anal sex — it is a fundamental safety and comfort requirement.

How to Apply Personal Lubricant
For vaginal sex: Apply to the vaginal opening and to the penis or toy before penetration. Add more as needed during sex — if sensations shift from smooth to rough, it is time to reapply. There is no wrong amount.
For anal sex: Apply generously to the anal opening externally and internally. Apply to the condom, toy or body part being inserted. Reapply whenever sensation changes — do not push through friction.
For masturbation: Apply to the genitals before and during solo play. Start with a moderate amount and add more as desired. Water-based and silicone-based both work well.
With a condom: Apply to the outside of the condom after it is in place. Never apply lubricant inside a condom or before putting it on. Water-based or silicone-based only with latex condoms.
Choosing a Body-Safe Personal Lubricant
For a genuinely body-safe formula, look for: pH-balanced (3.8–4.5), glycerin-free, fragrance-free and paraben-free. Low osmolality (below 380 mOsm/kg per WHO guidelines) reduces cell damage risk. Products registered as CE or UKCA medical devices meet higher testing standards. For a complete guide to selection, see our page on how to choose the right lube.
