I recently interacted with a prostitute while highly intoxicated. She said she gets checked for stds every two weeks. A condom was used for oral sex and vaginal sex, but I did perform oral sex on her without any type of protection for my mouth. I am very worried. I do not have any symptoms but it has only been a few days. What are the chances that I contracted an STD? How soon should I get checked out to ensure nothing is wrong?
