Can I imagine a theoretical scenario in which fingering could transmit HIV or other STDs? Sure. If immediately before fingering you, he had sustained a deep, overtly bleeding cut, AND if he were a gay/bi man or IV drug user. Or if he had herpes, intentionally scratched a fresh herpes lesion then used that finger in you. Or maybe some other scenario.
In other words, don't worry about this. In 30+ years in a busy STD clinic (15,000 patient visits per year), I never once saw or even heard of a patient who had acquired any STD by fingering. It just doesn't happen.
The worst possible source of accurate information about HIV transmission is web postings by people with wild claims. I will bet there nobody in the world ever acquired HIV by fingering. People who post such claims either are lying; or don't understand that other exposures actually were the source of infection (e.g., the guy who is "sure" he didn't get it from his wife, but who fingered another woman); or are in denial about what their real risks were.
Assuming you are sexually active outside a single, mutually monogamous relationship, you should be tested for STDs (chlamydia, gonorrhea, syphilis) and HIV from time to time, like every year or so. If you haven't been tested recently, this would be a good time, since it's on your mind. But not because of the fingering event.
Good luck-- HHH, MD
I just want to THANK YOU so much for replying to my post. I feel 300% better than I have in a week!!
Keep up the great work you do!!
No, you don't need testing. All is well.
Thank you SOOO much for putting my mind at ease. I am actually NOT sexually active outside of a monogamous marriage. I've been married for 10 years (with 3 young kids) & this is the first occasion that anything like this has happened! Girls weekend, stupid drinking at a bar, met some young guy (24), didn't think someone I was basically just hugging & barely kissing would put his hands down my pants & do that! I won't call it an assault but never the less it was not a welcomed move!!! So can I assume that the need for testing (STD/HIV) is not necessary as this is the only incident outside of my marriage???
