I had unprotected oral sex with a positive man. Mainly he was a receiver, the action was quite intense. Also I did rimming. He ejaculated on the body (not mouth). I noticed a bit of pre-cum on his penis during the action. My gums are not bleeding, I never saw any sores in my mouth or blood while brushing my teeth. I am not aware having any STi (and what if I have?). He claimed that he was on treatment. Please evaluate my risk. Thank you.
Thank you for your inquiry. From what we gather from the question, you were asking about the chance of acquiring HIV through performing oral sex without a barrier. 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 scenario mentioned above does meet the three components of the transmission equation (1). Performing oral sex without a barrier is an activity that may allow semen direct access to the bloodstream allowing for HIV transmission (2). Although the risk of this activity is low, it has been attributed to causing new HIV infections (3).
For further information on HIV risk among sero-discordant sexually active couples, with the HIV-infected partner on effective treatment, please refer to the PARTNER study (4).
Recommendation: Refer to a physician for HIV test.
