Hi
Yes, it is possible that HIV can be passed if a man has anal sex with a woman without using a condom. HIV can be found in rectal mucous and enter the penis while having anal sex.
There are also other STIs that can be passed with unprotected anal sex. Have a look at our “Know your chances” page. It provides information on your chances of getting or passing an STI, depending on how you are having sex.
