Estimated risk of HIV exposure?

[Overcast2]

I’m a 24 year old gay man, 15 days ago I had a random sexual encounter with another man who’s status is unknown. Exactly 7 days later I woke up with a tender jaw and slight pain radiating from the lower back of my gums to my lymph node just below which felt tender, I also had a burning sensation in my throat and tongue, initially I thought it might have been LPR considering I had been drinking and smoking the night before, I’m also a mouth breather so I’m prone to dry mouth, however these symptoms persisted for 4/5 days before they became less and less frequent. I have been reading about the HIV risks of insertive oral sex from various sources that either say it’s a low risk or no risk at all, this hasn’t helped my anxiety considering I have to wait another two weeks before I could get tested. I would like to have an idea of the level of risk I have exposed myself to considering the only act was insertive oral sex and I had no cuts, sores or open wounds on my penis however I am not entirely sure whether the receptive partner had bleeding gums or cold sores. I’m aware that symptoms aren’t always a good HIV identifier and Google is not a search tool for self-diagnosis and yet most of my time the past week has been consumed by my health anxiety. Looking forward to hearing from you. Thanks

Oral is zero risk, not low risk. We rely on expert doctors whereas low risk sites might be using theoretical risks that have never manifested, so it is quite useless to worry about that.
HIV is instantly inactivated in air and also in saliva which means it is effectively dead so it can't infect from touching, external rubbing or oral activities. It doesn't matter if you and they were actively bleeding or had cuts at the time either because the HIV is effectively dead.  
Only 3 adult risks are the following:
1. unprotected penetrating vaginal
2. unprotected penetrating anal sex
3. sharing needles that you inject with. Knowing these 3 are all you need to know to protect yourself against HIV. Your situation is a long way from any of these 3.
Even with blood, lactation, cuts, rashes, burns, etc the air or the saliva does not allow inactivated virus to infect from touching, external rubbing or oral activities. The above HIV science is 40 years old and very well established so there is no detail that you can add that will make your encounter a risk for HIV. No one got HIV from the situation you encountered in 40 years and likely no one will in the next 40 of your life, so there in no more likelihood of HIV transmission happening than of you getting hit by a meteor as you read this.

It is best to avoid Googling cold turkey because there is nothing useful there - if you know the above 3 risks HIV prevention is simple and doesn't require lots of study.

Thank you! I appreciate your reply, though it is hard to ignore the symptoms considering they appeared exactly a week after the exposure, I have never really had LPR for 3/4 days straight along with a tender lymph node in my jaw

No malady follows a schedule, and you don't have HIV.
