A female condom (now more commonly called an internal condom) is a barrier method of contraception and STI prevention that’s inserted into the vagina or anus before sex. It gives the receptive partner more control over protection. Made of nitrile or polyurethane, internal condoms are compatible with all lubricant types and are a good option for people with latex allergies.
