<human>: Can you succinctly summarize the text in 1-3 sentences?

So I dated my ex-boyfriend for two years in college. Since I was like 13 I'd very occasionally (like once a year *maybe*) have cold sores on my lip. Through some super-shitty stroke of non-luck, I managed to give my ex-boyfriend genital herpes (HSV1) via going down on him. (I didn't have an active cold sore at the time cus I'm not an idiot, but had had one recently, during which we didn't have contact). 

It almost destroyed our relationship - I was completely distraught and felt horrifically guilty for not somehow having taken some extra precaution. He was also fucking destroyed and felt like it was a death sentence on his sex life forever. We stayed together for another year though and recently broke up. He never had any other outbreaks. I haven't had any cold sores since. 

The problem arises now - been on some dates with a guy and things are heating up. I guess my question is two-fold: **1)** should I talk to guys about the possibility of this happening? Would you??? I feel like people who have had cold sores generally don't bring it up the way one would a genital STI so it almost seems unnecessary, but it *has* happened to me so what now? And if I do decide I want to warn guys of the slight possibility, **2)** how do I do so without implying that I gave my last boyfriend herpes? Not for my sake but his - he was very adamant that no one ever know that I gave it to him, and our circles have drifted apart but are still close enough that the dots could be connected quite easily.
<bot>: gave ex-boyfriend herpes. Do I bring it up with future partners, and if so, how do I do it in a way that doesn't imply ex-boyfriend has it...?
