Thread: White bumps on labia, anyone know what this is!?

I had sex for the first time unprotected and 4 days later I noticed 2 small red bumps on my labia, 5 days after sex the bumps are now white. They kind of looked like white heads but the white part peeled off very easily, didn't hurt, and no fluids came out. Now the spots where the white peeled off look like little spots of red flesh. The area is a little tingly and itchy. I also have a sore throat and am coughing up mucus, I don't know if this has anything to do with it because my sister is sick with a sore throat too and I could have caught it from her. Anyone know what this could be? Please help I am very scared this could be signs of an std
