Std? Herpes? Or not concerning

I went out on a first date with a guy and near the end we started talking about relationships and dating and for some reason the decision of kissing on the first date got brought up and he said he can’t kiss me today so I kind of just looked at him and waited to hear why and he said I have a cold sore problem, I’m on medication for it but can’t today. I was shocked he just told me that and kind of processed it and he changed the subject immediately. I didn’t want to be rude and ask either bc I have no idea weather we even want to see each other again but does this sound like herpes? Does oral herpes automatically mean you have it down there too? Or no way to tell?
