I was having unprotected sex with a man for 3 years already. We never had a problem and then recently we broke up and I believe he might have had sex with other girls while still with me the past month. Last time we have sex waa about two weeks ago. On Friday I had sex with a new guy and we used a condom at first but then it started to be a little painful because the condom dried out. This morning I woke up with pain while urinating. Mainly because my vagina is still sore from Friday, and a yellow mucus. Can you please tell me what this might be a possible treatments?
