Sexual fluid

HIV is infectious in semen (cum) and pre-cum, in vaginal fluid and in rectal mucus.

Pre-cum has a lower risk because there is generally less of it. Some men can have more pre-cum than other men have cum. This risk is clearly related to other factors like viral load.

If there is no exchange of an infectious body fluid, HIV cannot be transmitted.
