3 days ago, I had an encounter with a sex worker. I had protected sex but prior to intercourse I did not wear a condom. I engaged in vaginal rubbing with my penis. I am 33 yr old male. 3 Days after, I have the following symtoms,
1. Extreme irritation / pain when urinating
2. Red inflamation on meatus
No other symtoms. What is it likely to be? What course of action should I take
