The major risk that you describe above is from your having your partner's penis in your rectum, not from the fact that a small amount of his genital secretions might have entered your mouth. the risk of HIV form oral exposure is 100-fold higher, at least than oral exposure.
So what was your risk. It would be silly to say that this was a nor risk exposure, it was not. On the other hand, the chances this fellow was HIV infected is rather low, both on a statistical basis (most bisexual men do not have infection) and because he said he was not infected. Considering your rectal exposure, in the unlikely situation that he had HIV, your risk of getting HIV from a single exposure is still only 1 in 100.
Should you get tested, yes. Should you worry?, no. Wait until about 6 weeks following your exposure and get a test. A test at that time will detect over 95% of infections acquired 6 weeks earlier and, when considered in context, will show that you did not get HIV from the exposure you describe. If you wait until 8 weeks after your exposure, the fact is that your test will have detected over 98% of all infections.
Hope this helps. Your risk is low. At the same time, risk is cumulative SO, as you have other partners PLEASE use condoms. We would like your low risk to become no risk. EWH
You do not need to send your questions repeatedly. These questions are answered as time is available. Be patient.
Penetration is penetration. Indeed partial, brief penetration is probably lower risk than full penetration and longer duration but, as you can imagine, there is just no way to study the effeect of such variation. There is greater risk for receiving (1 in 100) than being on top (penetrating) in rectal sex (1 in 200) bu tthere is still some risk.
As I said, your risk is low. EWH
Hi Dr Hook,
Thank You for your prompt response. Just wanted to clarify a couple of points.
I was not penetrated, it was the other way round. I was not fully in his rectum, half way I think. The duration was at the most was for a minute there was no thrusting, ejaculation etc.
Does this change your risk assessment? Does the risk increase if you are the bottom as appose to the top?
His HIV status is unknown, although he was as inexperienced and nervous as me.
Again thank you.
