The exposure you describe was virtually zero risk; if your HIV test had been positive, I would have been 100% certain you didn't acquire it from the exposure you describe. In any case, your negative HIV test at 6 weeks is almost 100% reliable.
The spitting in water test for yeast infection is flat-out quackery. It is total BS and means nothing. In any case you don't describe any symptoms that suggest yeast infection.
Happy holidays-- HHH, MD
Your risk is close to zero, NO Penetration NO HIV, touching gentials (frottage) is safer sex.
Handjob= NO risk
Getting Licked Penis or Blow Job = Close to Zero Risk.
Your over all risk is close to zero.. Relax you are fine.
Enjoy Your holidays
I am not a doctor...but i have been following lot of forums and have learned a lot about HIV transmission.
Lets see what doc has to say.
Unprotected Insertive Oral Sex is "almost" impossible with an infected person. The "almost" bit is the slight and possibly unusual circumstance that may occur when there are apparent sores, cuts or ulcers in the infected mouth that comes into contact with a sore, cut or ulcer on the uninfected penis.
So even though the official guidelines state that "Oral sex can also transmit HIV" on many websites without detailing explanations tp this transmission and the very very low risk if any, is not generally correct. They are absolutely right that it can be transmitted, but it is so extremely low to be even considered.
There have been very few documented reported cases of Receptive Oral Sex. This may be cos the semen may have come into contact with open sores or cuts in the mouth, but even in this case it is not for certain.
But there have been no documented cases of Insertive Oral Sex.
According to Doc HHH, I believe that he will say6 weeks is conclusive in your case.
