We know that gay men are at higher risk for HIV. What about lesbian women?

HIV is a virus without any preference of sexual orientation, gender, race, or class. It is important to remember that just because a couple is composed of two women, neither party is immune to HIV.
HIV can be transmitted when infected blood and/or vaginal secretions come into contact with a woman's genitals, mouth or with open cuts anywhere on the body. Hence, it is important that when making physical contact to cover the hand with a latex glove. Nothing should be inserted directly in the vagina or around the genital area or anus after it has been in a woman's vagina. This can spread vaginal infections and STDs.

Oral sex between lesbians may still pose a threat for HIV transmission. A dental dam, a split latex glove, or condom is recommended as safety precautions to be used during lesbian sex in order to protect both parties.
