Welcome to the Forum. It would be incorrect for me to say that there is no risk from this exposure but the risk is low, Here are the facts:
1. Statistically it is unlikely that your partner had an STD of any sort.
2. If she did, most, most exposures to infected partners do not result in infection.
3. There is no risk for STD from kissing, virtually none from condom protected vaginal sex, and little risk from either giving or receiving oral sex.
So, what would I do? I doubt that there is any great urgency for you to get immediately tested. On the other hand, it is probably a good idea and good for your peace of mind to go on and get tested for the major STDs of concern. These are tests for gonorrhea, chlamydia and non-gonococcal urethritis. I hope my comments are helpful. EWH
