Girlfriend came over with herpes simplex virus 1. Cold sore on lower left part of lip. Had Abreva covers, swore by them. Put it on to cover up the coldsore and I made out with her. Later on it fell off so I didn t want to kiss her anymore, but could help but to kiss her on the cheek. When I did, a few times she brushed up against my cheek and neck with the cold sore. What are the chances I have herpes simplex virus, and if I did contract the virus from the interaction, how long until I know whether or not I have it? How long would it take for a cold sore to appear, or this infamous tingle I hear about, etc.
