I was recently diagnosed with HSV-1, I received the test after an initial outbreak of a cold sore (accompanied by a high fever). I am negative for HSV-2. I am single . Am I ethically obligated to inform my dates that I have HSV-1 before even kissing them? Or before having sex with them? If more than 50% of the population has it, then chances are my date has it too and doesn't even know it. What is the right thing to do? A kiss is so spontaneous, a discussion about HSV1 before a kiss is obviously a mood killer. I have only had that one cold sore, no recurrences, and would obviously not kiss anybody if I had an active cold sore. What do people think?
