so about a month ago i hooked up with another guy. we mainly just kissed, and his penis was in my mouth but there was no cum that i recall that i had in my mouth. when he cummed it got on the skin on my leg, but i saw no cuts on any kind on it. my question is this a risk at all with cum on the skin with cuts?
Thank you for your inquiry. From what we gather from the question, you were asking about acquiring HIV through giving oral sex and from semen coming into contact with intact skin. From the information given, this scenario is determined to be Low Risk (Evidence of transmission occurs through these activities when certain conditions are met).
The act of giving oral sex is a low risk activity, but, semen coming into contact with intact skin is an example of a No Risk scenario (transmission of HIV is not possible in the given scenario).
Giving oral sex does meet the three components of the transmission equation. The transmission equation requires that HIV positive bodily fluid comes into contact with HIV negative bodily fluid through a high risk activity that has direct access to the bloodstream (1).
Bodily fluids that can carry HIV include: blood, semen (including pre-ejaculate), vaginal fluids, breast milk, and rectal secretions (1). Direct access to the bloodstream can be through cuts, tears, rips, mucous membranes, open sores, or needles (1).
A high risk activity can lead to transmission when bodily fluid has direct access to the bloodstream. These high risk activities include: unprotected sex, sharing needles, unsafe tattoos or piercings, or vertical transmission–from mother to child (in utero, during delivery, breastfeeding) (1).
In the oral sex scenario, the transmission equation is satisfied due to the possibility of bodily fluid having direct access to the bloodstream.
Semen coming into contact with intact skin does not satisfy the transmission equation. The bodily fluid is present in this situation, but there is no direct access to the bloodstream through intact skin.
Due to your Low Risk encounter, we recommend you seek HIV testing.
Recommendation: Refer to Physician for HIV test.
