With regards to HIV, I agree with anxiousnomore that you had no risk with what you describe for HIV. HIV is transmitted only in the following ways, unprotected vaginal or anal sex (no condom WITH penetration) and sharing IV drug needles. Those are the only ways that HIV is really transmitted. Oral involves both air and saliva so that it is not a risk as both of those inactivate the virus and this would include even if she had a mouth issue like sores or bleeding.
There is a herpes forum. However, one thing to point out is that if you had oral sex, you are talking about oral or mouth herpes to your genitals. That's herpes simplex 1 and not genital herpes which is simplex 2. Incubation is typically around 4 days and the range is 2 to 12 days. All other herpes questions, you should ask on the herpes forum.
Your situation involves personal contact with an object in air ( mouth, lips, cuts, blood etc.). No hiv worries, because you can't get hiv from personal contact except unprotected penetrating vaginal or anal, neither of which you did and you didn't share hollow needles to inject with which is the only other way to acquire hiv. Analysis of large numbers of infected people over the 40 years of hiv history has proven that people don't get hiv in the way you are worried is a risk.
HIV is a fragile virus in air or saliva and is effectively instantly dead in either air or saliva so the worst that could happen is dead virus rubbed you, and obviously anything which is dead cannot live again so you are good. Blood and cuts would not be relevant in your situation since the hiv has become effectively dead, so you don't have to worry about them to be sure that you are safe.
There is no reason for a person to test when they are safe. The advice took into consideration that the other person might be positive, so move on and enjoy life instead of thinking about this non-event. hiv prevention is straightforward since there are only 3 ways you can become infected, so next time you wonder if you had a risk, ask yourself this question. Did I do any of the 3? Then after you say "No, I didn't" then it's time to move on back to your happy life.
