8 days ago I briefly performed oral sex/cunnilingus on a woman I met that day at a party, and I am concerned about the chances of contracting an STD.
To my knowledge she did not have one already, and no penetrative sex took place, so for those reasons I am beginning to feel I may just be panicking. One detail I feel is worth pointing out however is that at the time she was menstruating. She was wearing a tampon so I did not make contact with that area, focusing only on the clitoris. I did not see any menstrual fluids. I performed this act for approx 30 - 45 seconds.
I have read online (including this website) that the risk of contracting HIV this way is extremely low (almost non-existent), and that STD transfer from female to male in this fashion is also very low risk.
I have not witnessed any physical symptoms listed online that relate to infection such as sores, etc.
Therefore my questions are: how long should I wait before going for any tests as I am anxious to put this behind me? With it only being a week since the event, am I right in my belief tests at this point would not be of any use? Assuming I entered your own clinic with the above scenario, what tests would you feel were warranted? Finally, if I had sexual intercourse with another person, how soon after exposure would it be possible for me to transfer anything to them?
