Three days ago I got oral sex from a guy that I don't know it was very quick I took out my penis from his mouth after that next day I was very concerned that we didn't take care so I got very nervous when I noticed teeth marks on my penis so I got very scared. Therefore I started to investigate in Internet and the only conclusion is that there is low risk of getting his trough the wounds or the urethra if the receptive has his positive it might be his blood and saliva and also red about saliva is not a good medium for the his. And the only way to be tranquil is waiting 3 months for the test... So I'm feeling very stress I'd appreciate any advice from your professional staff about what should I do in my case... Thanks greetings from Mexico

HI there, thanks for contacting the AIDS Vancouver Helpline/Online with your HIV related questions and concerns. We are happy to help!

I understand you're concerned about the risk of acquiring HIV from the encounter you had. Hopefully I can clear this up for you.

In your case, receiving oral sex is considered to be a Negligible Risk. This means that although you can technically make a case for it, there has never been a single reported case of acquiring HIV this way. Additionally, you're correct in saying that saliva doesn't work well to transmit HIV. This is because it contains an enzyme that helps to break the virus down. So the only way to really get HIV through receiving oral sex, is if there was a considerable amount of blood in the mouth, which is very rare and normally due to major dental work.

IN terms of testing, you're correct that 3 months is when HIV tests are considered conclusive. However, most tests are 95-98% accurate within 4-6 weeks, with results being highly unlikely to change after this time. So if you did want to get tested earlier to alleviate some of your stress, this is an option. However, keep in mind your risk level for this activity is virtually close to 0, but at AIDS Vancouver we recommend all sexually active individuals get tested regularly as part of their health routine.

Check out the BC CDC HIV Testing guidelines [HERE](http://www.bccdc.ca/NR/rdonlyres/B35EDEBD-98CA-48BB-AB7C-B18A357AC19D/0/BCHIVTestingGuidelinesMay2015.pdf).

Also, check out the HIV transmission equation which makes it easier to visualize exactly what 3 components are needed for there to even be a risk of transmitting HIV:

HIV TRANSMISSION EQUATION


BODY FLUID
+
ACTIVITY
+
DIRECT ACCESS TO BLOODSTREAM
---------- -------- ----------------------------
• blood (including menstrual) • unprotected anal or vaginal intercourse • vagina
• semen • sharing needles • anus
• pre-cum • mother to child (in specific cases) • urethra in the penis
• rectal secretions • open cuts and sores (in theory)
• vaginal fluids • other mucosal membranes
• breast milk • points of needle injection
Hopefully this helped!

Sincerely,

Christina
