We unfortunately have no statistics about HSV 1 transmission either mouth to mouth, mouth to genitals or genitals to mouth. I wish I had something I could tell you but I don’t. However, it is true that people shed less over time and recur less as well, which you already know from your own experience. Depending upon your age, there is a good chance that someone you are kissing also has HSV 1 infection already in which case your infection would not be a problem.
Please feel free to ask follow up questions as they come to you.
