I have to kiss two men in a play, and i am worried about possible herpes. neither have sores at the moment, but recently my bottom lip has felt weird?

Very low risk: This could be a risk if you haven't had oral herpes. (If you have, you're highly resistant to a new infection with HSV1.) But the risk is very low if neither of your fellow actors has a cold sore. I would guess that without a visible outbreak, less than one kiss in 10,000 leads to herpes. "Felt weird" isn't a herpes symptom. If no visible sores on their lips, you shouldn't worry. Break a leg!
