Is penile-vaginal intercourse risky for HIV transmission?

Yes. Penile-vaginal intercourse (fucking, screwing, getting/being laid) is high risk for HIV transmission. Proper use of a condom and lubricant will greatly reduce the risk of HIV transmission during intercourse.

All of the conditions that make HIV transmission likely are in place in this activity.

The majority of HIV cases in the world are a result of unprotected heterosexual intercourse.

In this activity, women are at much higher risk than men; receptive penile-vaginal sex (being fucked, being screwed) is one of the highest risk sexual activities for HIV transmission.

Despite this, there is lots of evidence to show that men are at high risk as well. There is evidence that HIV transmission can occur directly through the urethra (opening at the tip of the penis).
