I've done a lot of reading on this site, but havent found a question like mine
Im a 20 year old male and early thursday morning at like 1 or 2 am my roommate took 2 puffs off of my black and mild, the kind with the white mouth piece. I did not see any signs of a cold sore that whole day and night. The next day I see the beginnings of a cold sore on his bottom lip towards the corner, but not in the corner. He smoked from the center of his mouth and the next day he told me that it did not touch the sore. Of course at the time I had no idea and took it back from him maybe 5-10 seconds and continued.
So, should I be worried about contracting HSV1? I know the statistics of most people already having it, but still, Im worried. What are my chances of getting cold sores?
Also, in the worst case scenario, lets say someone has an oozing sore on their lip, but takes a sip of a straw or a drag of a cig so that the sore does not touch, what are the chances of passing it?
