What is 69?
69ing, or doing 69, is sharing oral sex with your partner; in other words, it’s giving and receiving oral sex at the same time.
Oral sex is when people use their mouths to stimulate another person’s genitals.
Oral sex on a woman is called “cunnilingus.” On a man it’s called “fellatio.” Anyone — girl or guy — can give or receive oral sex as long as she or he is comfortable with it and wants to engage in in oral sex.
Oral sex cannot cause pregnancy. But it can pass on infections, whether the person is giving or receiving genital stimulation. These infections include gonorrhea, syphilis, chancroid, herpes, hepatitis B, cytomegalovirus, human papilloma virus (HPV), herpes, and, rarely, HIV and chlamydia. Oral sex is generally less risky for these infections than unprotected vaginal or anal sex, but there is still some risk.
Using a barrier can reduce the risks. For safer oral sex, use a condom to cover the penis, or a Sheer Glyde dam, cut-open condom, or plastic wrap to cover the vulva or anus.
