I forget to mention that my cunnilingus to her is not protected and she also did protected fellatio to me.
Without knowing what STD your partner had, it's impossible to answer this question.
I agree with Life360 - you should get tested. While cunnilingus is lower risk than vaginal, you still have a risk for syphilis and gonorrhea. Even with protected sex, you have a risk for syphilis, HPV and herpes.
