Hello! I would first like to thank you all for the amazing work you are doing for the people, I have been going through vast array of informations on this website and found all of them very helpful.
I hate to admit it but, I had a sexual encounter with a sex worker exactly 8 weeks and two days ago. During the session, we had protected vaginal sex for about five minutes, she rimmed me for about a minute after, gave me unprotected oral sex, then I fingered her and masturbated my penis with some vaginal fluids present on my hand (I am circumsized, but my inner foreskin is still exposed as it was done when I was 16). What mentally destroyed me about this incident is that during the following month, I have had recurrent mouth ulcers.
I understand that use of condom during vaginal sex with fairly effective and that unprotected oral sex is negligible risk. However, I have been having trouble finding information regarding having vaginal fluid on hand and then touching penis, and receiving rimming. Are there any risk in these activities?
Also, I have taken OraQuick tests at 3 and 6 weeks post exposure, which came back negative. Is this result accurate or do you recommend that I retest at 8 weeks or 12 weeks?
A very concerned man in Florida.
Thank you for your inquiry. From what we gather from the question, you were asking about the risk of acquisition of HIV from anilingus and the efficacy of the OraQuick tests. Receiving oral sex and anilingus fall in the negligible risk category because they do involve the exchange of body fluids. However, there has never been a confirmed report.
Vaginal fluids have the potential for carrying HIV, but in the above scenario the status of the partner is not known. Also, there is no direct access to the blood stream (via cuts on penis for the vaginal fluids to gain access) therefore the overall risk of acquiring HIV through vaginal fluids in this scenario is negligible. The Centers for Disease Control and Prevention (CDC) does not recommend the use of in home HIV testing because they can yield false-negative results 
Recommendation: We recommend testing by the 4th Generation(EIA) method. For more personalized answers refer to a physician.
