###Human: I received oral sex for only two minutes. Am I at risk of HIV? ###Assistant: Hello. I have noted your concern. Unprotected insertive oral sex with an HIV positive woman has a negligible/non-existent risk of transmission of HIV for the male partner unless she had oral sores or blood mixed saliva or bleeding gums which might increase the risk. You have had two episodes of a sore throat after this sexual encounter which can be because of seasonal flu and change in weather. I have a few questions.  The sore on your gum could be more of a dental problem rather than an STD. I suggest you take oral Metronidazole 400 mg, thrice daily in addition to the Amoxicillin that you are already taking. Also apply Metrogyl DG gel (Metronidazole), twice daily. Regards. For more information consult a dermatologist online -->
