I almost had oral sex with a woman with a cold sore. She put her mouth on the head of my penis, barely. It was for 1 sec. Should I worry about gen herpes?

The cold sore is now known to be meaningless as an indication of infectiousness. 75% of us have herpes type one. Once you have this common infection you cannot get it again. Ever.
