Im 24 Year Old Healthy Female. Two Nights Ago I

Im 24 year old healthy female. Two nights ago I had unprotected sex with someone who told me they’re positive for herpes 1 & herpes 2 from the igg blood test, but he felt like he didn’t need to tell me bc he never experienced an outbreak. Obviously I’m freaking out! What are my chances ofbecoming infected from him? I don’t remember seeing any blemishes or bumps or blisters. Now that I think of it he may have had a rash on his knee but with that indicate herpes? How would it travel to his knee?
