How to talk about sexual health with a partner: a practical guide

AltFTool Health Editorial TeamFact-checked 6 min read

Quick answer

Talking about sexual health with a partner means discussing STI testing, contraception and personal boundaries before you become intimate, ideally at a calm, private moment. Using simple, non-judgemental phrases and sharing your own information first makes the conversation easier and shows care for both of you.

Key points

  • The best time to talk is before you are intimate, when you are both calm and sober.
  • Leading with your own plans and results makes it feel shared rather than like an accusation.
  • Asking about testing and contraception is a normal part of caring for your health.
  • A partner's reaction tells you something useful about how they handle your wellbeing.
  • Sharing test results, or testing together, is a simple way to build trust.

Why should you talk about sexual health with a partner?

Many sexually transmitted infections cause no symptoms, so neither person can tell from how they feel whether they have one. Talking about testing and protection is the only reliable way to make shared decisions about safer sex.

These conversations also cover contraception, which affects both partners, and boundaries: what each person is and is not comfortable with. Couples who talk openly about these topics tend to feel more trust and less anxiety.

When is the right time to bring it up?

Choose a relaxed, private moment before you are intimate, rather than in the middle of things. Being sober helps both people listen and think clearly. A walk, a meal at home or a message conversation can all work, depending on what feels natural for you.

It is also worth coming back to the topic when things change, such as before stopping condoms, after either of you has had another partner, or when you are thinking about changing contraception.

What can you say to start the conversation?

Plain, friendly wording works best. Starting with your own information makes it feel like teamwork rather than a test of the other person.

  • "Before we go further, I like to make sure we are both tested. I was last tested in March. When was your last test?"
  • "What are you using for contraception at the moment? I would like us to decide together."
  • "I would like us to use condoms for now. Is that OK with you?"
  • "Is there anything you are not comfortable with, or would like me to know?"
  • "Would you be up for getting tested together at a clinic?"

How do you handle a difficult reaction?

Some people feel embarrassed or defensive at first, especially if they have never been asked before. Stay calm, explain that this is something you do with every partner, and give them time to think. Many people are relieved once the topic is raised.

If a partner mocks you, refuses to discuss protection, or pressures you to drop your boundaries, take it seriously. Someone who respects you will respect your health decisions. You never have to go ahead with anything you are not comfortable with.

How should you share STI test results?

Sharing results can be as simple as telling a partner the date and outcome of your last test, or showing a results message from a clinic if you both want to. Remember that a test only covers infections up to its window period, so a recent exposure may not show yet.

If you test positive for an STI, your clinic can help you tell current and recent partners, and many services can notify partners anonymously. A diagnosis is common and treatable or manageable, and telling partners protects their health.

When to get help

  • Get urgent help within 72 hours if you think you have been exposed to HIV, to ask about PEP.
  • Speak to a pharmacist or clinic as soon as possible after sex without contraception, or if contraception has failed, about emergency contraception.
  • Book a sexual health check if you or a partner have symptoms, or before stopping condoms with a new partner.
  • Seek support if a partner pressures, threatens or controls your sexual health decisions.

Frequently asked questions

Is it rude to ask a new partner if they have been tested?

No. Asking about STI testing is a normal, responsible part of looking after your health and theirs. Framing it around yourself, for example by saying when you were last tested, helps it feel like a shared decision. Most people appreciate a partner who takes their health seriously.

What if my partner says they have never been tested?

That is common, and it is not a sign that anyone has done something wrong. You could suggest testing together or separately before you stop using condoms. In many countries, including the UK, sexual health clinics are free and confidential, and home testing kits are widely available.

Do I have to tell a partner if I have an STI?

Telling partners is strongly encouraged so they can be tested and treated, and so you do not pass the infection back and forth. Laws on disclosure differ between countries. A sexual health clinic can advise you, and many can contact partners for you without revealing your name.

    STI testing: when to get tested, how it works and what to expect

    Get tested for sexually transmitted infections (STIs) if you have symptoms, a new partner, unprotected sex or a partner who has an STI, and as part of routine check-ups. Most tests use a urine sample, a swab or a blood test, are confidential, and many infections cause no symptoms, so testing is the only way to know.

    Choosing contraception: methods, effectiveness and what to consider

    The most effective contraceptives are long-acting methods such as the implant and intrauterine devices, which prevent more than 99% of pregnancies because they do not depend on remembering anything. Pills, patches, rings and condoms work well too but are less effective in everyday use. Only condoms also protect against sexually transmitted infections.

  • Consent & communication

    Understanding consent: what it means and how to ask for it

    Consent is a clear, willing agreement to take part in sexual activity, given freely by someone who is able to make that choice. It must be informed, apply to a specific activity, and can be withdrawn at any moment. Silence, pressure or a lack of resistance never count as consent.
