BLEEDING GUMS (kissing an rim)


Thank you for all of these useful information in regards of STDs. I have a query that is eating me alive. I am hypochondriac, so you can imagine how stressful it is. I had one night stand with a man with unknown status. We were kissing passionately for about 20-30 seconds, and I noticed that he had bleeding gums. We stopped the kissing and I spit on the tissue to check if I have it as well, luckily I did not have it at that very moment. Right after that I examine my mouth and gums and I noticed that my gums started to bleed as well - not excessive amount, just around one teeth, that I rinsed and bleeding disappeared right away. We did not kiss any more, however I received rim job after that (at the time of rimming, his gums were not bleeding any more). I would really appreciate If you can tell how big this risk of transmission is. Thank you a lot for your time and effort to help us.



Thank you for your inquiry. From what we gather from the question, you were asking about acquiring HIV through taking blood into mouth and anilingus. 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. The transmission equation requires bodily fluid that is HIV positive come into contact with bodily fluid of an individual that is HIV negative by having direct access to the bloodstream through a high risk activity.

Bodily fluids that contain HIV: 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).

High risk activities include: unprotected sex, sharing needles, unsafe tattoos or piercings, vertical transmission–from mother to child (in utero, during delivery, breastfeeding) (1).

The scenario of taking blood into the mouth satisfies the transmission equation because of the exchange of bodily fluids from the bleeding gums could transmit the bodily fluid containing HIV to the individual who is HIV negative. The bleeding gums could have direct access to the bloodstream through cuts in the mouth of the other individual. It was noted by the individual that they discovered their own gums to have blood which can provide possible evidence of bodily fluid exchange.

The scenario of anilingus is considered to be a Negligible Risk (There are no evidence or no documented cases of transmission). There is a chance of the exchange of bodily fluids through this scenario, but there has never been a confirmed report acquiring HIV through this act. In the scenario of anilingus there may be blood or rectal secretions exchanged through a cut, tear, rip, or mucous membranes. In the case of no barrier/protection the exchange of bodily fluids would be more likely to occur and thus have an opportunity for HIV transmission to occur. (2).

Recommendation: Refer to Physician for HIV test.
