I am a middle aged male. I recently received oral sex from a new partner. As I am usually very safe with new partners, the oral sex was performed with a condom on. Upon departing for the evening I noticed the girl had what appeared to be a cold sore on her lip. It was fairly small and appeared scabbed over. I'm baffled I hadn't noticed this sooner. I'm now terrified that I may have been exposed to HSV-1 or HSV-2.
1. What is the possibility of transmission? Should I be concerned?
2. I have no symptoms but is accurate testing for HSV-1 or HSV-2 possible without symptoms?
