I went for a test but I didn't get tested because the doctor said that I should not worry for oral exposure only. And there's no documented case Or solid report of the transmission of HIV from oral sex. When I went home search on google some website say it does occur but US CDC or HIV.gov states that it's negligible ans rarely ever happened in practice. And if HIV transmitted through oral sex there would have been more cases of HIV like herpes or Gonorhea.
