I had my last relationship late 2018. I got tested 3 months after last encounter and came back negative for HSV 1/2, HIV, Gonorrhea, Chlamydia and Syphilis.
In mid-2020, I had an encounter with an old friend in my car, no oral sex was performed. I only received a handjob which she constantly licked her fingers to simulate my penis head. I never had contact with her vagina or vagina fluids, only with her breasts. We did kissed.
I am now in a relationship and I am sure the STD/I question is soon to come up, should I retest or disclose about the encounter I had in 2020? Is it possible to have contracted Gonorrhea, Chlamydia or Syphilis from the handjob due to her saliva?
