in regards to HIV, you shold not be worried at all. To the right of your screen is an article that discusses HIV and oral sex.
Thanks - I will try to relax.
Welcome to the forum.
I understand your concern. But the odds of any STD, especially HIV, are very low. The average risk of HIV for the oral partner by fellatio, if the penile partner has HIV, has been estimated to be around 1 in 10,000. That's equivalent to giving BJs to infected men once daily for 27 years before transmission might be expected. No STD, including HIV, causes sinusitis symptoms (i.e. nasal congestion, runny nose, etc).
The major problem here is probably related to a sexual choice you regret, i.e. a psychological/emotional issue. The chance you caught any STD is small. However, it was a high risk exposure, and it would be reasonable for your to visit your local health department STD clinic for STD testing -- and perhaps also an HIV test, for reassurance. Most likely all results will be negative.
I hope this helps. Best wishes-- HHH, MD
