Condom Use Guide: Types, Tips, and Safe Sex Basics

Condoms are one of the most common and effective tools for protecting against sexually transmitted infections (STIs) and unplanned pregnancy when they are used correctly every time someone has sex. Learning how to choose, check, and use them the right way is an important part of taking care of your sexual health.

Why Condoms Matter for Teens and Young Adults

Condoms are considered a barrier method of protection. They work by blocking semen, vaginal fluids, blood, and other body fluids from passing between partners. When used the right way, external (“male”) condoms can greatly lower the risk of:

• Unplanned pregnancy by keeping sperm from reaching an egg
• Many STIs such as chlamydia, gonorrhea, and HIV
• Some infections spread by skin contact, although not all areas are covered

Because teens and young adults have some of the highest rates of STIs, health organizations strongly encourage condom use whenever there is vaginal, anal, or oral sex.

Types of Condoms and What They Are Made Of

Not all condoms are the same. Knowing the differences can help you choose the one that fits your needs and any allergies you may have.

External (“male”) condoms

These condoms go over an erect penis and are the most commonly used type.

• Latex condoms: The most common type; highly effective and stretchy.
• Polyurethane or polyisoprene condoms: Useful for people with latex allergies.
• Textured or ribbed condoms: Designed to change sensation, but protection depends on proper use, not texture.

Internal (“female”) condoms

Internal condoms are worn inside the vagina or anus. They have a ring at each end and are made from synthetic materials like nitrile or polyurethane.

• Can be inserted before sex so there is less interruption.
• Offer similar protection against pregnancy and STIs when used correctly.

What about natural or “skin” condoms?

Some condoms are made from animal membranes (often called “lambskin”). They can help prevent pregnancy, but they do not reliably block viruses that cause STIs such as HIV. Because of this, major health organizations do not recommend them for STI protection.

Pre-Use Checklist: Things to Check Before You Put a Condom On

Before using any condom, a quick safety check can lower the chance that it will break or fail during sex.

How to Open and Handle a Condom Safely

Many condom failures happen before the condom is even on, simply from rough handling. To avoid accidental tears:

• Push the condom to one side of the wrapper before tearing.
• Tear along the edge with your fingers; do not use scissors, knives, or teeth.
• Be gentle with fingernails, jewelry, and braces so you do not scratch the condom surface.
• Once open, do not unroll it completely in your hands; it should be rolled on directly.

Step-by-Step: Using an External Condom the Right Way

External condoms only work well if they are used from start to finish of every sexual act.

Before any genital contact

• Wait until the penis is fully erect.
• Make sure there is consent from everyone involved.
• Use a new condom every time you have vaginal, anal, or oral sex.

Putting the condom on

• Check the direction: The rolled ring should be on the outside, like a little hat ready to roll down.
• Pinch the tip with your fingers to leave space for semen; this also pushes out trapped air that can cause breakage.
• Place the condom on the tip of the penis and roll it all the way to the base while still pinching the tip.
• If uncircumcised, gently pull back the foreskin first so the condom fits smoothly.

During sex

• If the condom starts to roll up, pause and roll it back down carefully.
• If it comes off or tears, stop, withdraw, and replace it with a new one before continuing.

After ejaculation

• While the penis is still erect, hold the rim of the condom at the base to keep it from slipping.
• Carefully withdraw from your partner, still holding the condom in place.
• Slide the condom off without spilling, tie a knot if you want, wrap it in tissue, and throw it in the trash (not the toilet).

Lubricants: What Helps and What Hurts

Lubrication lowers friction, which can both make sex more comfortable and reduce the chance of the condom breaking.

Lubricants that are condom-friendly

• Water-based lubricants (often sold near condoms in pharmacies).
• Silicone-based lubricants, which tend to last longer.

Lubricants and products to avoid with latex condoms

Certain products weaken latex and increase the chance of breakage, so they should not be used with latex condoms.

• Baby oil, mineral oil, or massage oils
• Petroleum jelly (like Vaseline)
• Body lotions or creams
• Coconut oil or other cooking oils

Some condoms have added spermicide called nonoxynol-9. Health authorities do not recommend this for STI prevention because it can irritate the genitals and may actually raise infection risk in some cases.

Using Condoms for Different Kinds of Sex

Condoms are not only for vaginal sex. Many STIs can be passed through anal and oral sex as well.

Vaginal sex

• Use a new external condom or an internal condom every time.
• Make sure the condom stays on from start to finish.

Anal sex

• Use a new condom and plenty of condom-safe lubricant because anal tissues are delicate and more likely to tear.
• Never move the same condom from the anus to the vagina or mouth.

Oral sex

• An external condom can be used on the penis during oral sex to reduce the risk of STIs.
• For oral-vaginal or oral-anal contact, a dental dam (a thin latex or polyurethane sheet) can provide a barrier.

Common Condom Mistakes and How to Avoid Them

Studies show that many people make similar errors with condoms, which reduces how well they work. Knowing these mistakes can help you avoid them.

• Putting the condom on late: It should be on before any genital contact, not halfway through sex.
• Taking it off too early: Keep it on until after ejaculation and withdrawal.
• Using two condoms at once: Doubling up can increase friction and make them more likely to break.
• Reusing condoms: Condoms are made for one-time use only.
• Not leaving space at the tip: Forgetting to pinch the tip can trap air and increase the chance of bursting.
• Mixing wrong lubricants: Using oil-based products with latex condoms weakens the material.
• Using the wrong size: A condom that is too tight may break; one that is too loose may slip off.

How to Store Condoms Safely

Even a high-quality condom can break if it has been damaged by heat or friction. To keep them in good shape:

• Store condoms in a cool, dry place like a drawer, small box, or bedside table.
• Avoid keeping them in your wallet or tightly packed pocket for long periods; body heat and pressure can damage them.
• Do not leave them in a hot car, near heaters, or in direct sunlight.
• Keep them in their original wrappers until it is time to use them.

What to Do If a Condom Breaks or Slips Off

Even when used correctly, condoms can sometimes fail. Knowing what to do next can help lower the risk of pregnancy and STIs.

If it happens during vaginal sex

• Stop immediately and withdraw.
• If you are worried about pregnancy, ask a health provider or pharmacist about emergency contraception, which is more effective the sooner it is used.
• Talk to a clinician about STI testing and follow-up, especially if you are not sure of your partner’s status.

If it happens during anal or oral sex

• Stop and replace the condom before continuing.
• If there was possible exposure to HIV or other STIs, ask a health professional about post-exposure options and testing.

Talking With Partners About Condoms

Using condoms is easier when everyone understands why they are important and how they work. Open, honest communication with a partner is a key part of safer sex.

You might find it helpful to:

• Discuss condom use before things get sexual instead of in the heat of the moment.
• Practice how you would ask a partner to use a condom so you feel more confident.
• Buy condoms together or agree on the type and size you both prefer.
• Remember that any partner can suggest condoms—it is about mutual protection, not blame.

Condoms and Other Birth Control Methods

Condoms are excellent for reducing STI risk, but other methods may provide stronger pregnancy prevention. Health organizations often recommend using condoms together with another method, such as birth control pills or an intrauterine device (IUD), for added protection.

• Condoms + another method = better protection against pregnancy and ongoing STI protection.
• Long-acting methods (like IUDs or implants) do not protect against STIs; condoms are still important.

Frequently Asked Questions (FAQs)

Q: How effective are condoms if used correctly?

A: When used the right way every time, external condoms are highly effective at reducing the risk of both pregnancy and many STIs, especially when combined with another form of birth control.

Q: Can I use an external condom and an internal condom at the same time?

A: No. Using an external and internal condom together causes friction between them and can make both more likely to tear. Use only one type at a time.

Q: Do I really need a condom for oral sex?

A: Many STIs, including gonorrhea, chlamydia, and syphilis, can spread through oral sex, so using condoms or dental dams can reduce the risk of infection.

Q: What if I am allergic to latex?

A: If latex causes itching, burning, or a rash, you can choose condoms made from polyurethane, polyisoprene, or nitrile instead. These still offer good protection against pregnancy and STIs when used properly.

Q: Do I need to be older to buy condoms?

A: In many places, condoms can be purchased at pharmacies or supermarkets without a prescription and without age limits. You can also often get them for free at clinics that provide sexual health services to teens.
