In order to contract HIV, infected bodily fluids have to enter your system. Considering this, having sexual intercourse without a condom would definitely put you at risk for HIV if your partner has it.
<em>HIV can be transmitted only through the contact of damaged tissue or mocous membranes with body fluids like blood, semen, pre-seminal fluid, rectal fluids, vaginal fluids, and breast milk.</em> As you can see in the image I added, the other options are not possible.
