Hi, so I had sex with an escort and what we basically did is she gave me unprotected oral sex, I licked her anus and we had vaginal sex with a condom, but the condom sliped a bit during interourse, so basically the elastic ring of the ondom was inside her vagina, but still covering most my penis. I don't know if she was HIV positive or not, but assuming she was positive, what are the chances of me getting HIV with this scenario? Please help, I'm quite uneasy about this.
