Six days ago I had unprotected sex. This partner has been safe in the past. Later that evening I started noticing burning from my vagina. I have a tendency to get irritated after sex, and I have reoccurring yeast infections. I've used monostat anti itch cream, no suppositories. It seems to help with the dryness and the burning, but it's never cleared up. Now I'm paranoid I have an std. So far, no bumps, sores, itching, odor,flu symptoms.
