Last week I have sex with my husband, it last for one hour, I was recently shaved and he gave oral sex and also I was dry. The sex was rough. Two days after that I got a few blisters over my vagina, it doen't hurt just feel it when pee. I went to the doctor and he prescribed me acyclovir and orderes me labs tests for herpes. Nine years ago I had something similar to all this and i was tested and the results was negative. I am worry because the blisters are spreading over my labia (they began in the outside of tha vagina). What is happening to me?
