I'd like to preface and say that I'm a bit of a hypochondriac, having a cold sore effects my anxiety levels negatively.

Mostly, I am concerned about transmissibility. I'm in my mid twenties and never had cold sores before. After (only) making out with a really cute girl, I later noticed a cold sore pop up on her lip... not much longer I got one.

I'm pretty bummed because I'll be honest, I love being intimate with women and I feel like this is really going to impact that. I don't want to give it to a future partner, but it seems I now have to give up my sort of cavalier attitude about kissing, intimacy, etc. Honestly I'm more worried about it effect an LTR.

Am I the only who is thinking about this? Am I overthinking? Do I need to tell future partners?
