I made out with a girl last night and be the jerk I am I did this while having a cold sore. The cold sore is completely scabbed over but Ive heard from different sources it is still contagious if not the most contagious at this stage. Is this true? Is it possible to be less contagious if the cold store is scabbed over and the tingly sensation is gone? Is it possible for someone to not get the virus even though they made contact with someone that does like an immunity or something?
