My boyfriend and I had sex over month ago, a couple weeks later I'm having symptoms of a yeast infection, another week goes by and bumps appear. We both got tested and he comes out negative for HSV 2 and mine positive. Now that last time we had sex he had a cold sore on his lip. Is it possible for me to get it that way? If so how come he was negative for type 2? We haven't had sex since that last time at all.
