Is sex good for you? Five benefits, without the hype

Is sex healthy, and what does that actually mean?

Sex can contribute to pleasure, relaxation and a sense of connection, provided you want it and feel comfortable and safe. It is not a miracle cure, though. You do not need to have more sex to earn a clean bill of health.

Something enjoyable that might also be good for you sounds like a lovely combination. Yet claims about burning calories, sleeping better and beating stress sometimes run ahead of the evidence. So what do we really know?

Here are five possible benefits, the research behind them and a few myths worth putting to bed. No performance targets. No weekly quota. Just room to discover what works for you and your partner.

The essentials

• Pleasure, consent and safety come first.
• There is no required number of times to have sex.
• A link in research is not a guarantee.
• Pain or worries deserve a conversation with a professional.

When is sex healthy?

Sex can be part of a healthy life when it is freely chosen, enjoyable and safe. That means more than how the body performs. Feeling at ease, being able to express your boundaries and enjoying the experience matter just as much. The World Health Organization describes sexual health in terms of physical, emotional, mental and social wellbeing.

Comparisons can also creep into worries about your body. Our Dutch guide to average penis length and circumference explains what measurements do, and do not, say about you.

You might immediately think of intercourse when you hear the word sex. Intimacy can also mean kissing, touching or simply lying close together. You do not have to work towards a particular finish line. An erection, penetration or an orgasm is not an exam you must pass to share a good moment.

The five benefits below are possibilities, not promises. Something that helps one person relax can create pressure for another. Your own experience, and your partner’s, are the starting point.

1. Feeling good: pleasure is a good enough reason

You may recognise that contented feeling after time together: a laugh, some attention, a little conversation afterwards. Sex can be pleasurable and satisfying. It does not always need a grander purpose.

A systematic review of 63 studies found associations between aspects of sexual health and wellbeing, including quality of life and life satisfaction. That does not establish that more sex makes people happier. The evidence could not demonstrate causation; health and wider life circumstances also matter.

Our practical suggestion is to ask yourselves whether you enjoyed the experience, rather than whether it was enough. A moment can still feel good even when it does not go as expected.

You have nothing to prove. A good moment for both of you matters more than a scorecard.

2. You move your body and use energy

Sex uses energy. How much depends on what you do and how long it lasts. The familiar claim that everyone routinely burns hundreds of calories is much too neat.

A small 2013 study involving 21 young, healthy couples measured an average of about 85 kilocalories per person per sexual encounter: approximately 101 for men and 69 for women. These were averages in a selected group, not a personal calorie calculator.

Your body is active, but that does not mean you can replace your usual exercise. Walking, cycling and other activity still have their place. An intimate moment need not become a workout where someone checks the stopwatch.

3. A break from the noise in your head

Work, children, shopping and a phone that never stops lighting up: some days your mind barely gets a break. Enjoyable time together can provide a pause, with attention for each other instead of another task to complete.

If emotional overload sounds familiar, our Dutch article on sex and intimacy after burnout explores the subject. Your recovery and your clinician’s advice remain the priority.

Relaxation is personal. When you are exhausted, worried or feeling obliged to perform, sex can add pressure rather than relieve it. A health claim is never a reason to talk yourself into sex you do not want. It is perfectly reasonable to prefer a cuddle, a conversation or some rest.

If the pressure centres on getting or keeping an erection, our guide to coping with erection problems discusses talking about it and seeking support. You do not have to work everything out alone.

4. Feeling closer to your partner

Intimacy can be a way of saying: I see you, I am listening and I like being here with you. It often shows up in small gestures: a hand on a shoulder, laughing together or asking what would feel good right now.

The number of times you have sex does not, by itself, tell you how well your relationship is going. Different preferences call for a conversation, not a competition. Explain what you miss without turning it into an instruction for your partner. You might say: I miss our quiet time together. What would you enjoy?

Our Dutch article on sex and relationships looks at differences in desire and expectations. For a gentle place to start, the Dutch guide to massage and attention includes simple ideas for shoulders, back and hands. Agree beforehand that a massage can remain just a massage.

5. Winding down and perhaps sleeping more easily

Some people feel sleepy after sex or orgasm. Others feel more alert or want to talk. Neither response, on its own, tells you how much someone cares about you.

In a 2019 questionnaire study with 778 adult participants, many reported falling asleep more easily or sleeping better after sex with orgasm. Not everyone answered every question, and sleep was not measured objectively.

That tells us something about people’s perceptions, not that sex is a proven treatment for insomnia. Enjoy feeling relaxed when it happens. If sleep problems keep affecting daily life, discuss them with your GP.

Sex and health in numbers: what can research tell us?

Numbers can quickly turn into promises. It helps to ask what was measured and what the finding cannot establish. Statistics about erection medicines need the same care; our Dutch article on how many men use erection medicines explains the difference between an estimate and a current count.

The studies are linked in the relevant sections above. Treat the figures as context, not targets for your own sex life.

Three health claims that need a little more context

Does sex work like a painkiller?

A pleasant experience can shift your attention, but describing sex as equivalent to two painkillers is not responsible general advice. Do not replace prescribed treatment with sex. Stop if sex hurts and discuss recurring pain with your GP. Pain is not a sign that you should try harder.

Does frequent ejaculation prevent prostate cancer?

That has not been established. A large American follow-up study found an association between more frequently reported ejaculation and fewer prostate cancer diagnoses. As an observational study, it cannot establish a guaranteed protective effect. It does not create an obligation to reach a particular number of orgasms.

Is more sex always healthier?

No. There is no weekly number everyone needs to reach. Thuisarts explains that desire varies between people and over time. Some people want little or no sex and feel comfortable with that. A healthy, enjoyable life does not require sexual activity.

Healthy sex starts with what feels right for you both

The most useful starting points are often simple. Make space for attention, and leave space to change your mind. Starting something does not mean you have to finish it.

• Ask and listen. Discuss preferences and respect a no or uncertainty. Earlier consent is not consent to everything that might follow.
• Let go of the script. Time together does not have to lead to sex. Choose what fits that moment.
• Think about protection. Correct condom use reduces the risk of sexually transmitted infections and pregnancy. Discuss contraception when pregnancy is not wanted. See Thuisarts on condoms.
• Take discomfort seriously. Stop when something hurts or feels wrong. Bring up symptoms that keep returning.

Worried about an infection after unprotected sex? Ask your GP or an appropriate sexual health service about testing. A sexually transmitted infection does not always cause noticeable symptoms.

When should you talk to your GP?

Make an appointment if pain, erection problems, a persistent change in desire or another sexual concern is troubling you. You do not have to wait until it feels serious enough. Uncertainty and anxiety are valid reasons to ask for help too.

Starting the conversation can be the hardest part. Write down what you notice, when it began and what concerns you. A simple opening is enough: I would like to ask something about sex, but I find it difficult to bring up. Thuisarts offers guidance on that conversation.

For questions about erection medicines, start with our English guides and comparison of sildenafil and tadalafil. Discuss personal use with a doctor or pharmacist.

Common questions about sex and health

Do you need sex to stay healthy?

No. Sex is not a health requirement. Desire differs and may change. If you are comfortable with little or no sex, an online average is not a reason to change that.

Is daily sex healthy?

Daily sex is not a goal you have to meet. Consent, comfort and protection matter. Continuing more often is not a good answer when someone has no desire, feels pressure or is in pain.

How many calories does sex burn?

There is no fixed answer. The small study described above found about 85 kilocalories per person per encounter on average. That finding cannot simply be applied to everyone.

Can intimacy be enjoyable without intercourse?

Absolutely. Touch, cuddling and quiet closeness can all be enjoyable. You decide together what feels right. An erection or orgasm need not be the goal.
