Actually I had an blow job (oral sex) with boyfriend in the month of march-april. He had tested hiv in the month of january with all medical checkup and all were normal and negative. Even I tested in the month of may for hiv elisa tridot, vdrl, hbsag, anti hcv and all cbc, lipid, renal, all came negative and in normal range. Should I still worry for hiv. Because too may questions are arising day be day on hiv. I want to know the higher chances of getting hiv transmission. And what are the chances of getting hiv through oral sex (blow job) and kissing.
