The UK Kink GuideEvidence-led glossaryProducts used to reduce contact with bodily fluids or skin and lower the likelihood of some infections and/or pregnancy. Protection depends on material, fit, correct use and the exposure involved.
Manual claim and limitation notes are shown where an individual source audit is complete. Other evidence-type labels are a publisher aid awaiting source-by-source confirmation.

In brief
External condoms, internal condoms and other barriers work by reducing particular contact. They do not offer identical coverage or protection for every infection. Choosing the correct product, lubricant and size improves comfort and reduces breakage; using two condoms together increases friction rather than safety.
Check the expiry date and package, open carefully and use a new barrier for each appropriate activity or partner. Follow the manufacturer's directions rather than improvising with untested materials.
Do not use two external condoms together or combine internal and external condoms; friction can increase failure.
A barrier worn on a penis or compatible object, available in latex and non-latex materials.
A barrier placed internally before sex, with product-specific instructions.
A sheet barrier used to reduce contact during some oral sexual activities.
A hand barrier useful in selected circumstances, with material and allergy considerations.
Oil-based products damage latex and polyisoprene condoms. NHS guidance recommends water- or silicone-based lubricant with latex; non-latex products require their own package instructions.
Allergy or sensitivity may require a non-latex option. Fragrance, additives and topical medicines can also affect comfort or compatibility.
Condoms reduce HIV, many STI and pregnancy risks when used correctly, but protection varies for infections spread through uncovered skin. No barrier promises zero risk in every context.
Contraception and STI prevention remain separate questions. Internal and external condoms are contraceptive options; other barriers generally are not.
If a condom breaks, slips or was used with an incompatible product, stop and replace it. Depending on circumstances, seek timely advice about emergency contraception, PEP, STI testing or hepatitis prevention.
Do not wash internally or use harsh chemicals in an attempt to prevent infection. A clinic can assess actual next steps.
