Female Condoms — The Complete Guide to Internal Condoms
Internal condoms — commonly called female condoms — are one of the most underused and misunderstood forms of protection available. They offer unique advantages that external condoms cannot, and they are suitable for people of all genders. Here is everything you need to know.
What Is an Internal Condom?
An internal condom is a barrier contraceptive worn inside the body rather than on the penis. According to Planned Parenthood, the term “female condom” is no longer preferred because people of all genders can use internal condoms — they can be inserted into the vagina or the anus.
The only FDA-approved internal condom currently available in the US is the FC2 Internal Condom, available at fc2condoms.com and some pharmacies and health clinics.
How Does an Internal Condom Work?
An internal condom is a soft nitrile pouch with two flexible rings — one at each end. According to the CDC:
- The inner ring (closed end) is inserted into the vagina or anus and holds the condom in place
- The outer ring (open end) remains outside the body covering the vaginal opening or surrounding the anus
- The condom lines the walls of the vagina or anus providing a barrier against both pregnancy and STIs
How Effective Are Internal Condoms?
According to Planned Parenthood, with perfect use internal condoms are 95% effective at preventing pregnancy. With typical use the rate is around 79%. Using internal condoms alongside another birth control method significantly improves pregnancy prevention. Like external condoms, internal condoms also protect against STIs including HIV when used correctly and consistently.
Advantages of Internal Condoms
- Can be inserted up to 8 hours before sex — no interruption in the moment
- Latex-free — made from nitrile, suitable for those with latex allergies
- Compatible with all lubricants — including oil-based
- The receptive partner is in control — does not depend on the other partner
- Can be used for both vaginal and anal sex
- Some people find they enhance sensation — the outer ring can stimulate the clitoris or perineum
How to Use an Internal Condom — Step by Step
For Vaginal Use
- Check the expiration date and open the package carefully
- The condom comes pre-lubricated — add more lubricant if desired
- Find a comfortable position — standing with one foot on a chair, squatting, or lying down
- Squeeze the inner ring at the closed end between your thumb and forefinger
- Insert the inner ring into the vagina like a tampon and push it as far up as it will go
- Make sure the condom is not twisted inside
- The outer ring should remain outside the vagina covering about an inch of the vulva
- Guide your partner into the opening of the condom — not between the condom and the vaginal wall
For Anal Use
- Remove the inner ring — it is not needed for anal use
- Insert the condom into the anus using your finger
- Leave the outer ring outside
- Use generous lubricant
After Sex
- Twist the outer ring to keep semen inside the pouch
- Gently pull the condom out
- Wrap in a tissue and dispose in the trash — do not flush
- Never reuse an internal condom
Important Rules
- Never use an internal condom and an external condom at the same time — friction causes both to fail
- Check that the penis or toy is entering the condom and not going around the side
- If the outer ring gets pushed inside during sex stop and reposition it
Where to Get Internal Condoms
- Planned Parenthood health centers — often free
- Some pharmacies including CVS and Walgreens
- Online at fc2condoms.com
- Community health clinics — often free or low cost
Internal vs External Condoms
Neither is universally better — they serve different needs. Internal condoms give the receptive partner control, can be inserted in advance, and are latex-free. External condoms are more widely available and less expensive. Many couples keep both on hand.
The Bottom Line
Internal condoms are a highly underrated option. They are effective, latex-free, versatile, and give the receptive partner agency over their own protection. If you have never tried one they are worth exploring — especially if you or your partner have a latex allergy or want the option to prepare in advance.
