I have given oral sex to a guy and during the first couple of days i had some pain in my throat. on the 4th day, i noticed a small spot on my uvula and i'm worried that it might be an STD. It has the same colour as my uvula and it makes me feel uncomfortable every time that i swallow.
I am aware that most STDs need about 2 weeks in order to show symptoms, but if it's not an STD, what might have caused this?
