Thanks for the post.
There is a theoretical risk that you have been exposed to HIV, syphilis, chlamydia and gonorrhoea with perhaps herpes also. I say theoretical because as you say, she says that all is well and we don't know that she has any of the diseases mentioned.
We do know that for at least part of the time you were having unprotected sex with a sex worker and your alcohol intake may mean that your recollection of the timings might be incorrect.
I understand why you were given the antibiotic and it might have been partly effective against some of the bacterial diseases mentioned.
I would though suggest that you have a full range of tests including HIV, syphilis, hepatitis B, chlamydia, gonorrhoea and NSU at the most appropriate intervals for the tests available in your locality.
kind regards, Sean
Sir even with the transmission rate so low for HIV do I have a serious worry on my hands I feel great after the antibiotics.... And it's been about a month now
