Should I tell him I got mouthherpes from the sun?

I had my kissed the guy I like for the first time yesterday. And when I got home I realised that what I thought was a pimple just on the beginning of my lip or what you say, is actually mouthherpes. Should I tell him or wait to see if he gets it too and then tell him?

Look, my mom had the virus and drank from my water bottle when we were at a vacation somewhat years ago, so I got it. It can come back from sun exposure. Jeez
