Whatever you are feeling is not hiv related. Hiv transmission risks occur in case of unprotected anal, vagnal sex and sharing drug works. Move on and your anxiety will disappear on its own. Do continue to have protected sex always.
I'm just scared because I have been having flu like symptoms including fatigue and being cold, but no fever or nausea for a couple of weeks.
You didnt have any exposure. Everything you did was protected. Oral sex is zero risk for hiv. You would have been fine without any tests.
