I had unprotected sex on 24th July with a sex worker. Then I doubt she might have stds. I request her for blood test and she agreed. Her report shows that she has herpes, HPV and chlamydia. Report is negetive for HIV, Hepatitis B and C and syphilis. My question is what is the chances of transmission of those stds. I have read somewhere that it is lie between 10-30 % if anyone has unprotected sex. There would be a chance I might not caught up with any of these. Also it's been more than 3 weeks and I don't notice any symptoms.
