Oral sex and fingering aren't high risky activities, but, it is still possible to get infected with HIV when performing them.
The risk is bigger when there are small skin or mucosa tearing and blood.
The most common early symptoms of HIV infection are fever, fatigue, and rash. Others include headache, swollen lymph glands, sore throat, feeling achy, nausea, vomiting, diarrhea, and night sweats.
Ask for tests such as the p24 antigen test and HIV PCR test that can give accurate results within three weeks of infection.
Best wishes!
