Recently, I had unprotected oral sex with my boyfriend (I sucked on his penis). He claims he is clean, yet he has a sordid past ( i realized he sleept around alot). the session consisted of two blowjobs, both times he came in my mouth and I immediately spit it out, i didn't have any cuts or sores, and i had brushed my teeth at least 2 hours before the encounter. I am terrified of the thought of catching HIV form that interaction. The encounter was 3 weeks ago. How soon can I get tested for it to be conclusive, and what are the chances of getting HIV. Also, I cannot tell my family, they would be very disappointed, so any support is appreaciated.
