I have recently changed birth control & last night, after intercourse, I had white rice-like dry pieces on the outside of my vagina! I have never seen anything like this. There was a lot of them, and I believe they had been pulled out of my vagina during intercourse.
I am very sure it has nothing to do with STDs. I did not think it was an infection because I do not have any of the other symptoms, but what else could it be?
