How do I tell my partner I tested positive for an STI?

When a test result comes back positive for an STI, your mind can race pretty quickly.

Will my partner still want to be with me? Will they think differently about me? Will anyone ever want me again? What does this mean for my sex life?

Those fears are understandable, especially when you don’t yet know what happens next. STIs carry a stigma that many other health conditions don’t, and it can be easy to jump from “I tested positive” to imagining every possible consequence at once.

But a diagnosis is information, not a prediction of what the rest of your life will look like.

Before attempting to have a conversation with your partner, start with your own health. The last thing you want to do is approach the conversation while your own worst fears are still filling in all the blanks.

Talk with a medical professional about what the result means, whether you need additional testing, and what treatment or management may look like. Ask what they recommend you do next.

You do not need to solve your entire future today.

What does STI treatment look like?

There isn’t one answer because different infections are treated and managed differently. Understanding those differences can help, especially when your mind is imagining the worst.

Some infections can be cured with appropriate treatment. Syphilis, for example, can be treated with penicillin (opens in a new tab), with the specific course depending on the stage of infection.

Other infections can’t currently be cured but can be managed. People living with HIV who receive effective treatment (opens in a new tab) can live long, healthy lives. Getting and keeping an undetectable viral load prevents sexual transmission of HIV (opens in a new tab).

Genital herpes remains a lifelong infection, but antiviral treatment (opens in a new tab) can reduce outbreaks and, in some circumstances, lower the risk of transmission to a partner.

None of that means a positive diagnosis should be dismissed or minimized. It means the first few minutes after seeing that result won’t give you the full picture of what comes next. A medical professional can help you understand what it means for you.

So take this one step at a time. Learn what the diagnosis means and what your doctor recommends. Give yourself a chance to move beyond the initial shock before trying to answer every question your partner might have.

And remember, you don’t need to wait until you have every answer. It’s okay to say, “I don’t know yet, and I’m finding out.”

Once you can separate what you know from what you fear, you’ll be in a better position to talk honestly. Let your partner know promptly, and before you have sex again, so they can get advice about their own health too.

How do I tell my partner I tested positive?

There is no perfect script for telling someone you have tested positive for an STI. But there are a few things that can make the conversation easier on both of you.

If possible, choose a time when neither of you is distracted, rushed, or already becoming intimate. Give yourselves some privacy and enough time for your partner to process what you’re telling them. Planned Parenthood’s guidance on talking about STI results (opens in a new tab) recommends a private setting where you won’t be interrupted.

Be direct. You don’t need a long introduction or an apology. You might simply say:

“I got my test results back and one of them came back positive for [STI]. I’ve spoken with my doctor and I wanted to tell you because this may affect you, too. Here’s what I know so far.”

From there, tell them what you actually know. If your doctor has explained what treatment looks like, share that. If your partner may need to get tested or speak with their own doctor, say so. And if there are things you don’t know yet, it is okay to say that too.

If you want to show them your results, you can share the relevant information privately without handing over your whole medical record.

Try not to fill those gaps with assumptions, including assumptions about where the infection came from. A positive STI result does not necessarily tell you when you acquired an infection or who had it first. Some infections can stay unnoticed for a long time. CDC’s advice after a positive gonorrhea or chlamydia result (opens in a new tab) explains that an infection may have begun in a previous relationship without either person knowing. The result alone isn’t proof that someone cheated.

It also means resisting the urge to manage your partner’s reaction by minimizing the situation. There is a difference between offering perspective and telling someone how they should feel.

You can explain what your doctor told you about treatment and transmission. You can reassure them that you are taking your health, and theirs, seriously. But they still get to decide what that information means for them.

Risk information is shared. Risk tolerance is individual.

Your responsibility is to give your partner the information they need to make their own decisions. Their responsibility is to decide what they’re comfortable with.

That may mean they ask questions or need some time. They may want to speak with their own doctor. They may want to change how you have sex for a period of time, or they may decide they aren’t comfortable continuing a sexual relationship.

You can hope for understanding without assuming what their answer will be.

If your partner is the one telling you

If you’re reading this because someone you care about has just told you they have an STI, remember that they may have been terrified to have this conversation.

You don’t need to decide immediately what the diagnosis means for your relationship. You also don’t have to pretend you’re comfortable with something if you aren’t.

Listen. Ask what they know. Avoid jumping to blame when it isn’t clear when or how the infection happened. If you need medical guidance about a possible exposure, testing, or prevention options, talk with your own healthcare provider. Your partner may still be finding out what the diagnosis means for them.

What happens after the conversation?

Ideally, the conversation gives both people room to approach the situation with honesty and respect.

But not every conversation will go that way. Someone may be angry or scared. They may need distance. And unfortunately, some people may respond with judgment or stigma.

You cannot completely control how a person responds. What you can control is whether you were honest, whether you shared what you knew, and whether you gave the other person the opportunity to make an informed decision about their own health.

And if there are past partners who may also have been exposed, there may be other conversations ahead.
