visited thailand few days ago. at pattaya met a russian commertial sex worker with whom had sex. the condom broke two times and was noticed within 2 seconds and replaced. the girl was not lubricated and that must be the reason for condom splitting. asked the girl of her status to which she confirmed that she gets tested every month and she does not carry infection. am in real tension and troubled. please tell the odds against chances of infection in this case.
