(NSFW) If you have herpes, how soon do you tell a potential partner?

I’d like to approach this question from both sides. Let’s say you have herpes and you’ve just met someone you really hit it off with online. When do you tell them about your condition? During the first conversation, after the first date, or after several dates? Do you tell them before kissing or just before sex? Now, from the other side. If you met someone and they told you they had herpes, how soon would you want to know about it? I know this may be hard to hear, however, would there be a time-line in hindsight that you’d prefer to know by?
