What are the risks of contracting oral STDs from kissing with vaginal fluids?

[komo1001]

Hi. I recently had an encounter in which I inserted my fingers into a partner's vagina as we kissed. She then licked my fingers and quickly began to kiss me again, with an open mouth and inserted tongue. Is there a possibility of contracting an oral STD (such as oral gonorrhoea, oral chlamydia, oral syphilis, oral HPV or oral herpes) from such an encounter?

Also... a separate but connected question: if I were to contract an oral STD and then to kiss and/or perform cunnilingus on a woman, could I pass-on the infection to her mouth or vagina?

Thanks in advance.

Normally, the most common STD transmitted by kissing is herpes, but you would have seen the lesions on that lady's lips.
If the vaginal fluid reached your throat there is risk of any other infection, like syphilis and gonorrhea. But to be honest the risk is really low.
If you are infected and you perform cunnilingus f course you can transmit those infections to this new woman, as oral sex exposes to those germs. But, one more time, the risk is really low.
