Risk of contracting HIV?

[Teodora]

Hello!
Thank you for this forum and all the info in it! I hope you can help me..
On May 22 I had unprotected oral sex with a guy who I knew for two weeks.He ejaculated in my mouth.I spit out immediately.At the moment I did this, I did not realize that I'm putting myself at risk of contracting HIV or any other STD...
In the days after that I lost my sleep and nearly went crazy over what I did.At the local clinic, they assured me that the risk of getting HIV this way is extremely low but still exists.
The next day I asked the guy to get tested for STDs and he agreed. His results came out negative for HIV and 7 other STDs. He assured me that he did not have any kind of sex for more than 8 months before being with me and therefore this is his real HIV status. I did the same tests on 4 june and they are all negative.
Being calm about our STD status, I had 6 more times of unprotected oral sex without ejaculation with him (the last one was on the 17 June).
Then I I found out that there's a possibility of a false negative HIV test result. And now I can't sleep again because this is all I think about - what if his negative HIV result is a false negative and I still put myself at risk? I decided to stop seeing him because I can't live with the fear anymore..

Here are my questions:
1. What are the statistics for the possibility of contracting HIV through oral sex?
2. When should I get tested? If I can't wait for the three month window period - can I ask for both a PCR HIV test and a regular antibody test in the end of August (at 2 months after the last possible exposure)? If the results come back negative,is this enough to be sure I don't have it?

please give me advice what to do...I realize that I'm paranoid but still I can't escape the fear..

Thank you !!

argeed with aak001,the odds are 1/10000,if you feel test make you self comfortable then just test,i see no risk here.

you had no risk. the chance that you had it is 1/10000 so its close to nothing. i personally dont think that you need testing but do it just to make your self comfortable if you want.
