Re: unprotected sex with sex worker in thailand
I think the guys on here would need more information, like where are you, who was the girl, was she a sex worker, do you have any cuts or other std's etc.
I think the risk for insertive vaginal sex is about 1 in 2000, and that's even IF she had HIV to begin with.
I wouldn't worry too much (I know it's hard not to) at this point. It seems like a long wait, but you have to just put it out of your mind and try and keep busy until it's time to get tested. The worst thing to do is make things worse by self-diagnosing and searching too much on the internet.
Oh yeah, and play it safe from now on.
good luck, I'm sure you're ok, for a single encounter. Don't drive yourself crazy thinking about it.
