Firstly, was it oral or anal and did you use a condom?
At this point, you're creating your own misery. Any test you take now will be both accurate and conclusive.
Oral sex, despite of being unprotected is not a risk. Condoms protect against HIV transmission.
HIV is essentially a sexually transmitted disease, risk for HIV contraction is when you insert your penis inside of a vagina or anus with out a condom. A finger is not a penis and therefore there is no risk involved.
You never had a risk and do not need to test, you are wasting your time worrying over something that is non-existent.
Please see a therapist for your anxiety, you dont have HIV, move on.
So an update. I went to see an ENT doctor about my tongue and he said it’s a yeast infection. Could I have had a yeast infection for over a year?! Is this HIV related?!
