he had unprotected intercourse
I doubt that he tested positive after a 3 month negative unless he had another exposure during the window period.Oral sex is zero risk even with mouth sores and it's the Hiv experts that say this.
p.s i have herpes symplex 1 so there might have been sores in my mouth while performing oral sex
i just recently got diarrhea all day today (could be to all the eating i been mix matching potato chips/wine/chicken/fruitcakes/chocolate i ate yesterday ?? due cuz of my anxiety ... is oct 28 - till dec 4 a good amount of time. thank you rain all this joint started happening ever since my close friends who i consider a brother told me he was hiv positive and that he was tested for syphilis and was positive and negative from hiv ... but then he tested again within 6 months and was hiv positive ... so thats my anxiety (p.s I just recently went to a therapist)
Your oral sex encounter was zero risk for Hiv infection and the test you had was accurate and reliable.No futher testing is required.You're safe.
