How would you react?

Men 40+ ideally... I (29f) have been dating a new guy (41) for a couple of months. We've been out a lot and have been intimate. Something recently made me think and I remembered I had a coldsore about 11 years ago. I have never had one since, was in a relationship at the time and for 10 years after that so just never thought about it, it's not something that's ever crossed my mind. (It has come about because my ex is now basically blackmailing me over this - he obviously remembered and I didn't!)

I realise now that I probably need to mention this to the guy, but no idea how to address it or how it's likely to be received?

For some background, he has been with a lot of people and openly admits to sleeping with prostitutes in the past...

How would you react? What should I say?
