I'm not sure if my mind is playing games on me, but I am obsessive with this, so, pls, help me.
I'm a woman and I was with a much older man. We had deep kissing and he fingered me (introduced one finger for about 15 secs in my vagina). I'm not sure but it is possible there was pre cum on his finger since he was touching himself a lot before that). I refused to continue and he got violent for a while, maybe that is the reason I am so scared. There was no oral sex, only that. I got tested 3 times, 4th generation,at 28, 32 and 35 days, non reactive. I'm planning to take another test by 8 weeks (60 days). Do you think that was a truly risky situation? Thanks
Hi there, and thanks a lot for contacting the AIDS Vancouver Helpline for your HIV/AIDS related health information. It seems you're concerned about the possibility of HIV transmitting during an encounter. We're happy to answer this question for you.

This is a no risk situation. To understand why, check out our transmission equation:

---------- -------- ----------------------------
• 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
You'll see in the chart that required for transfer are all of a fluid involved in transfer, an activity known to be involved in transfer, and direct access to the bloodstream. Fingering (even if there was a bit of pre-cum on his finger) is not considered an activity known to be involved in transfer, this is therefore no risk. Also consider that HIV is a very fragile virus that is rendered intransmissible as soon as it is exposed to the air. Any virus potentially in the pre-cum would be intransmissible as soon as it is expose to the air.

We at AIDS Vancouver recommend routine testing for all sexually active people. So if you've never had an HIV test or it's been a while, we'd recommend you go for a test. As for testing after this specific scenario, it is not actually necessary. That said, if you wanted to know your status conclusively after this situation, you'd need to go for a test at least 3 months (or 90 days) after the potential exposure. 4th generation tests at 28, 32 and 35 days are good indicators of your status. Here is a bit more information on the 4th generation test, where you'll see that it is considered conclusive at 3 months:


Thanks for contacting the AIDS Vancouver Helpline with your question. We hope it has been answered fully.

Test Name Method Window Period Conditions
4th Generation EIA Blood test that looks for antibodies AND p24 protein antigens. Commonly referred to as the "combination," "combo" or "DUO" test. P24 protein is detectable immediately after infection but only for the first few weeks. The antibody (ab) test has a window period of 4-12 weeks post exposure. This test is widely available in North America. Most HIV specialists consider this test to be conclusive at 6 weeks but official HIV testing guidelines still recommend re-testing at 12 weeks for conclusive results. Conclusive at 3 months post exposure. |
