my understanding is to get tested now, then get tested in another six months.  The link is information from University of Pennsylvania on the risks of unprotected sex.  Sorry that happened.  It happened to me about three years ago.  I've had myself tested annually after that and so far so good.

Yeah, that sucks. Ive had it happen to me a few times. I would say try to stay in touch with her for as long as you can. Even if that means you continue to use her "services". I lost touch with some of those ladies and the lack of information of not knowing how they are doing can leave you wondering. Everyone in this "biz", provider and providee alike, should be tested at least once a year anyway so just look at this as if its time to get your test for the year and try not to dwell over it, whats done is done. Good luck.

get checked for:
herpes type-2 antibody levels
hepatitis B & C
hiv
syphilis rpr

these are the main ones that can hide & go undetected until ......

it happened to me too

I was doing doggie to a very hot provider , the action was  very intense, I was pounding her very hard, fast, deep, you name it....and it was good, but suddenly it was immensely good, the difference in sensations was so big that I I took the decision right away to pulled out and there it was the funny ring...shit, after that I have seen her one more time then she went off the business for many months, but last friday she came back to work, so I'll see her again.

but, I got worried as hell, The doctor recently tested me for many std, hepatitis etc, but so far everything looks good
