saw similar post but I ask anyway. Kiss a girl last night, a little tongue, woke up and my upper lip tingler, look like a little swelling, no cold sore (yet) feels like it's coming - throat is a little scratchy ( we were outside and it was cold). 'm starting to get concerned. The girl had no visible sores or the likes. I worried. Could it be a STD? how serious? never had anything other than the occassional cold sore - the last one was years ago, in my nose and not visible to the eye. When will I see serious symptons, if this is serious....thanks
