Cold sores are caused by herpes simplex virus. It is possible to get oral herpes from someone's genitals or fluid that comes into contact with genital mucous membranes (i.e. sperm) "Genital Herpes is contagious via mucus membranes, found in the mouth, genitals, nose, eyes and anus. They contain a thick liquid in which Genital Herpes travels. Sperm and vaginal fluids will usually be mixed with the fluids from mucus membranes."
