Evening all. I've had cold sores most of my adult life. I usually get 3 or 4 per year. Anyhow. Yesterday I met a friend. We kissed and had oral sex. 3 hours later a cold sore appeared on my lip. No tingling, no signs 😫. Now my friend has never had a cold sore though she's had many sexual paetners, especially in her teenage years. This one off, what would be the chances she's now caught oral or genital herpes? I'm totally gutted.
