Also, I’ve had occasional night sweats and uneasy stomach but I’m sure that is stress/anxiety related. I think some type of std was acquired based on what I’m feeling I’m just scared HIV was also.
You were never at risk. Oral sex is inefficient for transmission of HIV.
The above assessment doesn't change even factoring, cuts inside of your mouth / bad oral hygiene or ingesting infected fluid.
Saliva and gastric acid in your stomach restricts HIV transmission.
You were never required to test, you don't need to test any further. You are clearly dealing with a lot of anxiety, please see a therapist to figure out the real cause of this irrational fear and provide you with treatment to overcome this.
HIV is not your concern.
Stress doesn't equal risk, remember that. Nor does guilt or regret. The risks for HIV are very straight forward. Unprotected vaginal or anal sex or sharing of IV drug needles are the only ways adults get HIV. Oral sex, giving and/or receiving does not transmit the virus. Air and saliva inactivate it. So, you had no risk.
