Can a man get infected during cunnilingus or performing oral sex on a woman

Can I get HIV from Cunnilingus?

Yes. Cunnilingus, oral sex on a woman, is considered "possibly unsafe" without a latex or plastic barrier. If the woman has her period or a vaginal infection, it's considered "unsafe." "Possibly unsafe" activities have a smaller chance of transmitting HIV than behaviors in the "unsafe" category (which generally involve semen or blood coming into contact with mucous membranes in the rectum, vagina, or mouth). "Possibly unsafe" activities do, however, carry a risk of HIV (and STD) transmission.
