Here is my situation. Last week I spent a day at the beach in direct sunlight (something I don't often do) and that night, kissed and performed oral sex on a girl I met that night. In the next few days I developed what I believe was a small cold sore under my lip, which healed in about 6 days. I also had a lingering mild sore throat during this time. Then, exactly 1 week after I kissed the girl, my sore throat returned more noticeably, and what I believe will be a new sore has now appeared in a different location, further away from my mouth. Right now it has a white dot surrounded by redness (not a pimple). With both sores, very mild tingling, no pain.
I really can't tell if I've had these cold sores before or not. Also, I've been in multiple relationships where there was kissing and oral sex, and never had a cold sore outbreak, or gave someone cold sores, to my knowledge. I did date a girl who had cold sores about 8 years ago, but nothing occurred there either.
My question is, does this situation sound more like a primary outbreak due to kissing (I saw no open sores on the girl, but I know due to viral shedding I can still get HSV1), or does it sound more like a recurrent outbreak triggered by the excessive sunlight? I know that the IgG test will be the best way to confirm this, but that won't be for some months to get the best accuracy, and I'm very concerned about passing this on to someone before then. I know most adults have it, but I've been with someone recently and no symptoms occurred, which could easily mean I didn't have HSV1 until now. Should I refrain from kissing people until I get my IgG test?
