My boyfriend and I are in a committed relation. We have been have sex for about six months. At the first of March I had a BV infection, and we had sex. After that he had some abnormal discharge so he went to the doctor. He tested negative to Chalmdyia and Gonorrehea. His symptoms seemed to dissipate. Then he noticed after having sex with me, his penis burned, and was red and raw. Within 24 hours of having sex the symptoms go away. I've been treated for BV, and everything seems ok as far as that goes. But I have noticed after we have sex my vagina burns. We have not been using condoms, and its almost like after he ejeculates I start burning. Then for 24-48 hours I feel burning, itching, and vaginal dryness. What is going on?
