Good news, you have zero risk for HIV.
You can't get HIV if you used a latex condom during vaginal.
HIV is inactivated in saliva and air which means it can't infect from oral which includes kissing. So those are 2 reasons you had zero risk. Double zero risk.
No one in 40 years of history got HIV from oral. Even with blood, lactation cuts, rashes, burns etc saliva and air do not allow inactivated virus to infect, so you had zero risk.
Self diagnosis is generally wrong, so you are wasting your time with no medical experience trying to be a Google doctor studying a rash.
