Your risk is very low. Condom protect and sex is safe sex and despite being drunk, it sounds as though you were careful to take precautions. In addition, your partner indicated they were "safe" and without STD?HIV, thus, they probably were (most people tell the truth). Even if your partner was infected (and he was probably not), and even if the condom broke (it did not), you chances of infection would be less than 1 in 100. Putting all of this together, your risk is miniscule. Do not worry.
As for your specific questions:
1. Very, very low
2. Irrelevant. You are wondering about ARS. Read any series of posts on this site and you will see that we NEVER endorse symptoms as an indicator of HIV risk, no matter what they are. In addition, the timing of your symptoms fits poorly with ARS.
3. OK, get tested, but with a regular serological blood test.. We recommend against the RNA PCR tests. The have a higher false positive rate than the standard blood test and are not recommended for this purpose.
Hope this helps. EWH
1. Your gum surgery had begun to heal well by the time of your exposure (no matter how your mouth felt) thus this does not increase your risk.
2, Plese re-read my comments about symptoms. I do not know how to be any clearer. Symptoms are are an unreliable indicator or ARS and an unreasonable indicator for HIV testing. I will not get into a debate with other sites. As you no doubt know, you can find sites on the net that will tell you just about anything you want to (or don't want to) hear about the ARS etc. You have to decide who you wnat to believe. My assessment is unchanged. EWH
Doctor, thank you very much.
If I may follow up ( I will not make a habit of this) with a bit more information/question:
1) I had gum surgery 2 days prior to this event; I do not know if that made my "mouth" more vulnerable or not...
2) My symptoms: fever, sinus problems, stuffiness, sore throat, ear "ache" has been getting worse ( it started about 3 days after). I understand your point on the timing "early"; yet I have read in many places it starts "few days" after the event; is this correct? I understand there is no absolute number of days but are there known cases (at least in your experience) that these symptoms exhibit 3-4 days after the event?
I am sorry to bother you again on this.
Thanks much Regards.
