Hi I am 36 years old and the other day I received unprotected oral sex from a sex worker advertising on a website. She said she had seen her Dr the week before and had no stds. During the encounter I inserted my fingers into her vagina for about 10 seconds and then rubbed the outside of her vagina along with receiving the unprotected oral sex. What are the chances I caught some kind of std? What things should I be looking out for? Im very ashamed and concerned now as i am in a relationship and cant bekieve i did this. Please help.
