Condoms, Dental Dams, and Beyond: Barriers That Actually Work

When it comes to safer sex, condoms usually get all the attention. But they aren’t the only barrier method available, and they aren’t always used correctly. Whether you’re having vaginal, anal, or oral sex, barrier methods help reduce the risk of sexually transmitted infections (STIs) while keeping things fun and worry-free.

Condoms: The Classic Choice

External (or “male”) condoms are the most common barrier. They’re worn over the penis and are effective at preventing both pregnancy and most STIs when used consistently and correctly. Internal (or “female”) condoms line the vagina or anus and provide similar protection, plus they give the receptive partner more control.

Latex is the standard material, but polyurethane and polyisoprene options are available for people with latex allergies. Adding water-based or silicone-based lube reduces the chance of breakage and makes sex more comfortable.

Dental Dams: The Unsung Hero

Dental dams are thin sheets of latex or polyurethane placed over the vulva or anus during oral sex. They act as a barrier against infections such as herpes, gonorrhea, and HPV. Many people skip them because they’re less common, but they’re simple to use and can make oral sex safer without killing the mood.

Gloves, Lube, and Creative Options

Latex or nitrile gloves can be useful for manual stimulation, especially if there are cuts on the hands or if nails might cause irritation. Gloves can also protect against transmission of infections through skin-to-skin contact. And while lube itself doesn’t block infections, using plenty of it with barrier methods reduces friction, prevents breakage, and makes everything smoother — literally.

Why Barriers Matter

Many STIs spread through skin-to-skin contact, bodily fluids, or microscopic tears during sex. Barrier methods create a physical layer of protection, significantly lowering the chance of transmission. They don’t remove risk completely, but when combined with regular testing and open communication, they are one of the most effective tools for protecting sexual health.
