First of all, you may already be infected with hsv1 and not know it. At least half the people in your age group have it and most don't know they are infected because they never get cold sores. But, let's assume you do not have it, the chances you go herpes in the way you did is about 0.001%. I wouldn't not worry about it. Even if you did catch it, I would not worry about it because it nothing more than a very irregular and very minor inconvenience for most infected people. Also, most the people you date from here on out will be infected with hsv1. That's a fact you need to accept.
