Types of condoms: materials, lube and how to use them well.
Most condoms are latex. If you or a partner is allergic, condoms made of polyisoprene, polyurethane or nitrile also help protect against pregnancy and STIs. Lambskin condoms help prevent pregnancy but do not reliably protect against STIs. Whatever the material, a good fit, the right lube and a fresh condom for every partner matter most.
Materials compared
Latex, polyisoprene, polyurethane, nitrile and lambskin: what each one does.
Condoms are one of the simplest, most effective ways to play safe, and the choice is wider than the shelf suggests. Four materials protect against both pregnancy and STIs; one protects against pregnancy only. This is general information from JoinTheSwing editorial, not medical advice.
01
Latex: the default, and the most studied
Most condoms are latex, a natural rubber. It is the material most of the research is about: in heterosexual couples where one partner had HIV and condoms were used consistently, the HIV-negative partner was 71% to 80% less likely to become infected, and consistent use also lowers the risk of chlamydia, gonorrhea, hepatitis B and trichomoniasis (CDC treatment guidelines, reviewed 2024). Use it with water-based or silicone-based lube only. Oil-based products weaken latex and can make it break. Skip latex if you or a partner has a latex allergy.
02
Polyisoprene: latex-free synthetic rubber
Polyisoprene is a synthetic rubber. It does not contain the natural latex proteins that cause the allergy, it is stretchy, and it gives similar protection against pregnancy and STIs (Cleveland Clinic, 2020). One honest caveat: CDC notes that synthetic condoms other than polyurethane have been studied less for STI prevention. Treat polyisoprene like latex when it comes to lube: no oil.
03
Polyurethane: thin plastic that takes any lube
Polyurethane is a thin plastic. CDC rates its protection against STIs, HIV and pregnancy as comparable to latex, and it works with both water-based and oil-based lubricants. It does not fit as tightly as latex, so it is more likely to slip off, and it usually costs a little more (Cleveland Clinic, 2020). A good fit matters even more with this material.
04
Nitrile: the material of the FC2 internal condom
Nitrile is another synthetic, latex-free material. It is best known as the material of the FC2 internal condom (Marfatia and colleagues, 2015), and some external condoms use it too. Planned Parenthood lists nitrile with the plastic condoms that help protect against both pregnancy and STIs, and notes that plastic condoms other than polyisoprene can generally be used with oil-based lube. Check the packet to be sure.
05
Lambskin: pregnancy only, not STIs
Lambskin, or natural membrane, condoms are made from sheep intestine. They help prevent pregnancy, but they do not reliably protect against STIs, especially viral ones, and are not recommended for STI prevention (CDC treatment guidelines; Marfatia and colleagues, 2015). Their pores are small enough to stop sperm but up to 1,500 nanometres across, more than ten times the size of HIV (CDC treatment guidelines). They are an option for pregnancy prevention with a latex allergy, not for playing safe with new partners.
Sources for this section: CDC, Primary Prevention Methods (reviewed 2024); Cleveland Clinic, non-latex condoms (2020); Planned Parenthood, Condoms; Marfatia and colleagues, Condoms: past, present, and future (2015). With a latex allergy, the American Academy of Allergy, Asthma & Immunology calls synthetic rubber condoms the best choice. For a deeper look at the latex-free options, read the non-latex condoms guide, and if you are choosing because of an allergy, see latex allergy alternatives.
Thin, ribbed and flavoured
Thin, ribbed, studded, flavoured: what changes, and what does not.
The shelf is full of variations: thinner condoms for more sensation, ribbed and studded textures, warming or cooling gels, and flavours (Cleveland Clinic, 2025). These change how a condom feels, not the basic rules. The material still decides which lube you can use and whether it protects against STIs, and the same steps for putting it on still apply.
Flavoured condoms are made for oral sex. Planned Parenthood advises people with a vagina to avoid flavoured products for vaginal or anal sex, because they can lead to irritation, yeast infections or bacterial vaginosis (Planned Parenthood). For oral sex on a penis, any latex or plastic condom works, and some people prefer an unlubricated one so there is no lube taste.
If a condom keeps breaking on you, Cleveland Clinic’s fit chart suggests trying a thicker material; if you feel too little, a thinner one (Cleveland Clinic, 2023). The same article notes that FDA-approved condoms made specifically for anal sex are now on the market. Beyond external condoms, the other barriers are internal condoms, worn inside the body, and dental dams for oral sex on a vulva or anus (see how to use a dental dam).
Lube and spermicide
The right lube helps a condom work. The wrong one can break it.
Water-based lube is safe with every condom. Silicone-based lube is safe with latex (NHS, 2024) and with the plastic condoms (Planned Parenthood). Oil-based products, including petroleum jelly, body lotion, baby oil, massage oil and cooking oil, weaken latex and can make it break (CDC, reviewed 2024), and polyisoprene reacts the same way. Polyurethane can generally take oil-based lube, and so can most other plastics, but check the packet if you are unsure.
More lube is usually better. Not using enough is one of the human errors behind condom failure (Cleveland Clinic, 2025), and a few drops inside the tip plus more on the outside helps stop a condom breaking (Planned Parenthood).
Spermicide is a different matter. CDC does not recommend nonoxynol-9, the usual spermicide, for STI or HIV prevention: it can disrupt the lining of the vagina or rectum, it has been associated with a higher risk of HIV infection and of urinary tract infections, and condoms with it are no more effective than condoms without it (CDC, reviewed 2024). Its how-to page simply says not to use it (CDC, 2024). Pick a lubricated condom without spermicide and add plain lube. For a material-by-material list, see which lube is safe with condoms.
How to put one on
How to put on a condom, step by step.
The steps below follow the NHS, CDC, Planned Parenthood and Cleveland Clinic instructions, which agree on almost everything. Practising once on your own, before it matters, makes the real thing easier.
Step 01
Check the date and the wrapper.
Look for the expiry date on the wrapper and the box. Squeeze the wrapper gently: you should feel a small air bubble, which tells you the seal is intact. Skip any condom whose wrapper is torn, or that feels sticky, dry or stiff once opened.
Step 02
Open it with your fingers, not your teeth.
Tear the wrapper along one edge and slide the condom out. Teeth, scissors, long nails and jewellery can nick the material without you noticing.
Step 03
Check which way it unrolls.
The rolled rim should sit on the outside, like a little hat. If you start it the wrong way round, do not flip it over: throw it away and use a new one, because it may already have picked up fluid.
Step 04
Pinch the tip and leave a little space.
Hold the tip to squeeze out the air, leaving a small reservoir at the end to collect semen. Then keep hold of the tip while you start to unroll it.
Step 05
Roll it all the way down before any contact.
Put the condom on once the penis is erect and before any genital, oral or anal contact, then unroll it to the base. If it will not roll down, it is probably inside out: start again with a new one.
Step 06
Add lube.
A few drops of water-based or silicone lube inside the tip and more on the outside make sex more comfortable and help stop the condom breaking. Match the lube to the material.
Step 07
Hold the rim when you pull out.
Afterwards, hold the condom at the base and withdraw while still erect, so it does not slip off. Take it off away from your partner, wrap it and put it in the bin, not the toilet.
Step 08
Use a fresh one every time.
A new condom for every act, every partner, and every switch from anal to vaginal sex. If an erection fades partway through, take the condom off and use a new one when you are ready again.
Sources for these steps: NHS, Condoms (2024); CDC, Condom Use: An Overview (2024); Planned Parenthood, How to put on a condom; Cleveland Clinic, Condoms (2025). If a condom breaks or slips off, stop, take it off and put on a new one (CDC), then read what to do if a condom breaks.
Common mistakes
Six common condom mistakes, and what works instead.
Condoms rarely fail on their own. CDC's treatment guidelines put breakage at about two condoms per 100 and say failures usually come from inconsistent or incorrect use rather than breakage. These are the slips worth knowing.
01
Putting it on partway through.
Contact before the condom goes on is the gap it is meant to close. Putting a condom on after genital contact is among the human errors Cleveland Clinic lists.
Roll it on before any genital, oral or anal contact, and keep it on until the end.
02
Wearing two for extra safety.
Two condoms rub against each other, and the friction makes one or both more likely to tear. The NHS, CDC and Cleveland Clinic all say one at a time.
One condom that fits, with enough lube.
03
Grabbing lotion, baby oil or massage oil.
Oil-based products weaken latex and polyisoprene and can make the condom break (CDC; Planned Parenthood).
Keep a water-based or silicone lube next to the condoms so the right one is always within reach.
04
Keeping condoms in a wallet or the car.
Heat and friction damage condoms over time. CDC says not to store them in a wallet, and Planned Parenthood says not to leave them in a pocket, car or bathroom for long periods.
Store them somewhere cool and dry, and move a few into your bag on the day you need them.
05
Sharing one condom between partners.
Cleveland Clinic names using the same condom with more than one partner during group sex as a common cause of condom failure.
A fresh condom for every partner, every time. Keep enough within reach that changing is easy.
06
Putting up with a bad fit.
In a survey of 436 men, those who said their condom fitted badly were more likely to report breakage (adjusted odds ratio 2.6), slippage (2.7) and taking it off before sex ended (Crosby and colleagues, 2010).
Measure girth, try a snug, standard or large size, and switch if it pinches or slips.
Sources: CDC, reviewed 2024; Cleveland Clinic, 2025; NHS, 2024; CDC, How to Use a Condom (2024); Planned Parenthood; Crosby and colleagues, Sexually Transmitted Infections (2010). Fit has its own guide: the condom size guide, or the short answer to what size condom you need.
Expiry and storage
Condoms expire. Store them like something you want to work.
Condoms generally last between one and five years, depending on the material, and every box and wrapper carries a date (Cleveland Clinic, 2025). Once it passes, the condom may not be effective (NHS, 2024). CDC’s guidance for latex is not to use a condom past its expiry date or more than five years after it was made (CDC, reviewed 2024).
Keep condoms somewhere cool and dry, away from sunlight and sharp objects. A wallet, a back pocket, a car or a steamy bathroom are the usual culprits for damage (CDC, 2024; Planned Parenthood). If a condom feels sticky, dry or stiff when you open it, throw it away and use another.
For a weekend away or a party, pack a small supply in a bag rather than a pocket, in the sizes and materials that work for you, with a lube that suits them. Some hosts put supplies out, but your own means never relying on someone else’s guess about your size or your allergy.
Choosing for feel
How to choose for feel without giving up protection.
Start with what the research is clear about: used consistently and correctly, condoms are one of the most effective protections against STIs, including HIV (WHO, 2025), and any condom use is better than none (CDC, reviewed 2024). A condom you enjoy wearing is a condom you will actually use, so it is worth finding one you like.
Most people fit a standard condom, and fit is the first thing to get right (Cleveland Clinic, 2023). Then choose the material: latex unless there is an allergy, polyisoprene for a stretchy latex-free option, polyurethane if you want to use any lube. Then try different thicknesses, textures and lubes; Cleveland Clinic compares it to finding jeans that suit you. Doing that at home, before a date or an event, takes the pressure off.
Keep in mind what condoms cannot do. They work best against infections carried in body fluids, such as HIV, gonorrhea and chlamydia. They lower the risk of herpes, HPV and syphilis only where the condom covers the infected skin (CDC treatment guidelines; Planned Parenthood). CDC’s consumer page and WHO both caution that condoms do not protect against sores outside the covered area (CDC; WHO, 2025). That is why condoms sit alongside regular testing, vaccines for HPV and hepatitis B, and honest conversations with partners. Read do condoms prevent HPV?, the STD testing guide and the play-safe guide for the rest of the picture.
Common questions
Condom questions, answered plainly.
What are the different types of condoms?
External condoms, worn on the penis, come in latex, the most common material, and in three latex-free plastics: polyisoprene, polyurethane and nitrile. All of those help protect against pregnancy and STIs. CDC singles out polyurethane as comparable to latex for both, and says the other synthetics have not been extensively studied for STI prevention; FDA labelling limits their recommended use to people with a latex allergy. A fifth type, lambskin, is made from animal membrane and only helps prevent pregnancy. Internal condoms, worn inside the body, and dental dams for oral sex are the other barrier options.
Are non-latex condoms as safe as latex?
Latex-free plastic condoms help protect against both pregnancy and STIs, and CDC's treatment guidelines rate polyurethane as comparable to latex. CDC also notes that the other synthetic materials, such as polyisoprene, have been studied less. For most people latex is the default; if you or a partner has a latex allergy, a synthetic condom is the right choice, and it is far better than no condom.
Do lambskin condoms protect against STIs?
No. Lambskin condoms do not reliably protect against STIs, especially viral ones, and are not recommended for STI prevention. They are made from animal membrane with tiny pores that block sperm but can let viruses such as HIV and hepatitis B through. They help prevent pregnancy, but for STI protection choose latex or a latex-free plastic condom.
What lube can you use with condoms?
Water-based lube is safe with every condom, and silicone-based lube is safe with latex and the plastics. Oil-based products, including petroleum jelly, lotion, baby oil and massage oil, weaken latex and polyisoprene and can make them break. Polyurethane condoms can generally take oil-based lube, but check the packet. Extra lube is welcome: it helps stop condoms breaking.
How long do condoms last?
Cleveland Clinic says condoms generally last between one and five years, depending on the material, and CDC advises against using a latex condom past its expiry date or more than five years after it was made. Check the date on the box and the wrapper, store condoms somewhere cool and dry, and throw away any that feel sticky, dry or stiff.
Can you use the same condom with two partners?
No. Use a new condom with each partner, for each act, and when you switch from anal to vaginal sex. Cleveland Clinic lists using one condom with more than one partner during group sex among the common human errors that make condoms fail. At a party that means keeping enough within reach that swapping to a fresh one is easy.
Is wearing two condoms safer than one?
No. The NHS, CDC and Cleveland Clinic all advise using one condom at a time. Two condoms rub against each other, and the extra friction makes one or both more likely to tear. One condom that fits, used from start to finish with enough lube, is the safer choice.
Are condoms with spermicide better?
No. CDC does not recommend nonoxynol-9, the usual spermicide, for STI or HIV prevention. It can irritate or disrupt the lining of the vagina or rectum, it has been linked to a higher risk of HIV infection and of urinary tract infections, and condoms with it protect no better than condoms without it. Choose a lubricated condom without spermicide and add plain lube.

Have a Latex Allergy? Here Are 4 Safe Non-Latex Condom Options
Allergist interview: latex allergy can cause itching, hives and swelling and, rarely, anaphylaxis; polyurethane and polyisoprene condoms give similar pregnancy and STI protection (polyurethane fits less tightly and can slip more); lambskin does not stop many STI viruses; see a doctor for a skin or blood test.
American Academy of Allergy, Asthma & Immunology
Latex Allergy
Symptoms range from a skin rash to hives, swelling, wheeze and shortness of breath; a combination of symptoms or trouble breathing needs immediate medical attention; if either partner has a latex allergy, synthetic rubber condoms are the best choice; natural skin condoms are not recommended for STI or HIV protection; an allergist can diagnose it.
Marfatia, Pandya & Mehta, Indian Journal of Sexually Transmitted Diseases and AIDS, 2015
Condoms: Past, present, and future
Review: natural (animal-membrane) condoms block sperm but do not protect against viral organisms such as HIV, which are smaller than bacteria; latex is less porous and a more effective barrier; latex allergy symptoms range from hives and itching to wheezing and low blood pressure.
Planned Parenthood
Condoms
Latex, plastic (polyurethane, nitrile, polyisoprene) and lambskin condoms; oil damages latex, and oil-based lube works with plastic condoms except polyisoprene; lambskin only helps prevent pregnancy; condoms work very well against fluid-borne STIs and somewhat less well against skin-to-skin STIs; avoid flavoured products for vaginal or anal sex; a condom cut open makes a dam.

How to put on a condom
Put it on before any genital contact and wear it the whole time; check the date and the air bubble in the wrapper; never flip an inside-out condom; a new condom for every act and when switching from anal to vaginal sex; a few drops of water-based or silicone lube help stop breakage; store cool and dry, not in a pocket, car or bathroom for long; oil damages latex and polyisoprene.

Condom Size Chart: Does Size Matter?
Most condoms fit most people; measure a fully erect penis with a flexible tape, girth around the widest part of the shaft; too big can slip off and too small can break; the FDA minimum length for external condoms is 160 mm; Trojan's standard condom is listed for a 4 to 5 inch girth; FDA-cleared condoms for anal sex exist; the fit troubleshooting chart.
