There are no symptoms of HIV that can be used for diagnosing or even gauging the need for an HIV test. You can go on risk only. Oral sex is not a risk, so there is no chance for HIV....therfore no need to test.
Your thread was closed becuase there have been thousands before yours that were similar. No risk exposures, like oral sex, with people fretting about HIV even though they have been told no chance of HIV. You did not get HIV from oral sex....move on
