Yes could be.
Either way, you have oral HSV1 and not at all likely to obtain an oral HSV2 infection.
Hi thanks for the reply. I will admit I'm always worried about herpes and other stds so start to check myself the next day, maybe that's stressful?
These will be oral HSV-1 related.
The sex itself would only be an issue if it rubbed your lip to cause a weakness that a cold sore might come through. Almost always though there will be a stress related factor at play. Were you anxious about the sexual contact? Do you have sex beaause you're stressed?
