i have a cut on outside my vagina that now looks blistery. this is about 2 days after shaving but about 2 months ago after shaving it was as tho i had blisters do we think herpes or something else seems to occur only after shaving i think as never noticed before. also i was in a realtionship when they came before and didnt hav anything after we broke up. i recently had an encounter and there another one so is it related to sex?
