Are you sure you remember this correctly? You were high.
I say this because CSWs use protection to protect themselves from you, not to protect you from them. Their livelihood depends on protecting themselves.
Most people, including CSWs, don't have HIV.
Even if you use condoms, transmission oh herpes, syphilis and HPV is possible. Condoms reduce the risk greatly, but it doesn't eliminate it. I'm not saying this to scare you, but to inform you.
I doubt she is evil. I wouldn't go there. But you did take some risk if you aren't sure if there was penetration or not. HIV is ONLY transmitted if you have unprotected and penetrating vaginal or anal sex or share IV drug needles. So, rubbing, frottage, etc. is not going to be a route to transmission of HIV. Air inactivates the virus. However, other things like herpes or syphilis would be possible. Only you know if there was actual penetration or not. If there is doubt, then go ahead and get tested yourself and the best way to do that is a 4th generation DUO test taken at 28 days or beyond. That is a result you can rely on. Other std's often present with symptoms like a sore or blisters. You can get a complete screening to be safe.
No idea what happened, we weren't there. Apparently, neither were you, in a manner of speaking. But if you're saying you were with a prostitute, this comes up on here and on other forums and believe me, prostitutes don't ejaculate. They might pretend to but they don't. They aren't interested in you at all other than as a way of making money. As for the rest, the only thing you can do is get tested, as you apparently were too stoned to pay attention to what was happening. Can't make it not have happened.
