Short answer
Say it before you have sex, once you know you like each other, in a couple of calm sentences: what you have, how you manage it, and that they can take their time. The conversation is almost always shorter than the dread that comes before it.

The short version
You owe a partner one thing before sex: the chance to decide with the facts. That means telling them which virus you have and where, that it can pass to them even when you have no symptoms, and what you do to lower that chance. It does not mean an apology, a medical lecture, or a promise about how they will react.
If you want the wording now, skip to the script. If you want to understand why this goes better than people expect, keep reading.
What they actually need to hear
Four things, and none of them takes more than a sentence.
- Which type you have and where: HSV-1 or HSV-2, oral or genital.
- That it can spread without symptoms, so "I'll tell you if I have an outbreak" is not enough on its own.
- What you do about it: daily medication if you take it, condoms, no contact during symptoms.
- That they can ask anything and take time to think.
Everything else is context. If they ask how common it is, the World Health Organization estimated that 13% of people aged 15 to 49 worldwide had HSV-2 in 2020. That is a population figure, not their personal risk; the transmission guide has the numbers from actual couples, with their limits.
When to say it
Before any sexual contact, and after you know there is something worth protecting. Telling a stranger in the first message feels like oversharing and usually is. Telling someone after you have already slept together breaks trust in a way that is hard to repair, whatever the medical risk turned out to be.
For most people that lands somewhere around the second or third date, at the point where it is obvious things are heading toward physical. Some people say it by text the evening before a date they expect to end at home. Others prefer to be in the room. Both work. What matters is that it happens before, not during, and not after.
On dating apps, many people say it after matching and before meeting. It costs you some matches who would have left anyway, and it saves you an evening with someone who was going to leave later.
What to say
Here is the whole conversation, the way it usually goes. Change the details to match your own diagnosis and what you actually do; do not claim medication you do not take.
YouI want to be upfront about something before we go further. I have genital HSV-2. It can spread even when I have no symptoms, so I take a daily antiviral and we'd use condoms. I like where this is going and I wanted you to know. Ask me anything, or take some time.
ThemOkay. How did you get it?
YouFrom a previous partner. I found out afterward. You don't need my whole history, but I'll answer what you want to know.
ThemWhat's the actual risk to me?
YouLower than the fear suggests, and not zero. In the one trial that measured it, daily medication roughly halved transmission over eight months. I can send you the page with the numbers so you're not taking my word for it.
ThemI think I need to sit with this.
YouThat's fair. Take the time you need.
By text, the same thing fits in three sentences: "Before we meet up, I want you to know I have HSV-2. I take daily medication and use protection, but there's still a chance of transmission. Wanted you to hear it from me first; happy to answer anything."
If yours is oral HSV-1, the cold sore virus, the norm is lighter: mention it when things are heading toward intimacy, never kiss or give oral sex during a sore or the tingle before one, and leave it there. The kissing guide explains why that is the accepted standard.

What people say back
Three things happen, in roughly this order of frequency. Some people say yes on the spot, because they already know someone with herpes or because the precautions you described sound like enough. Check what they understood rather than assuming; a yes from someone who thinks it only spreads during outbreaks is not an informed one.
Many people ask questions, and the questions are predictable: how you got it, what the risk to them really is, and what happens if they catch it. Answer the first honestly without a full history. Answer the second with the study numbers and their population, not a percentage invented to sound reassuring. Answer the third plainly: symptoms vary, treatment exists, and a clinician can tell them what it would mean for them.
Some people need a day or a week. That is a good outcome, not a bad one. Give them the space and do not chase.
If they say no
Thank them for hearing you out and let it end. Do not argue, do not send them studies they did not ask for, do not try to talk them into a different level of risk than the one they are comfortable with. Their no is a decision about their own body.
It will sting. That is normal, and it passes. What it is not is a verdict on you. Another person, with the same facts, will decide differently, and no statistic can tell you in advance which person that is.
Before you do it
Say the sentence out loud a few times when nobody is listening. The first time you say "I have herpes" should not be to the person whose answer matters. Practice takes the wobble out of your voice, and a level voice is most of what makes the other person take it as a fact instead of a confession.
Pick a moment with no clock on it: not on the way into a bedroom, not with a drink in hand for courage, not right after a fight. And drop the apology. You did not do anything wrong, and leading with "I'm so sorry" tells them there is something to be sorry about.
