I've recently had sex with someone knew, they wore a condom. But a day later I had sex with my ex bf who I dated for 2 years. He said he never had sex with anyone else. But after we had sex he has a tender penis tip and white flaky skin. My vagina has been burning, itching, and has a thick white discharge. I thought it was just another yeast infection until he told me about his symptoms. I'm freaking out thinking I caught an std or sti somehow through the condom and gave it to him. Please help!!
