Sexual Health and Consent: A Grown-Up's Guide to Casual Sex
Straight facts on the law, testing and protection.
What do consent and sexual health mean for a hookup?
Consent means both of you agree freely, with the capacity to choose, and either of you can change your mind at any point. Sexual health means condoms, testing when you sleep with new people, and knowing about PrEP and PEP. STI tests are free at NHS sexual health clinics; South Africa's government offers free HIV testing at public health facilities.
None of this is the dull part; it's what lets two adults relax. XXX Direct is 18+ only, and like our other safety guides, this one names its official sources.
Consent: what the law actually says
The wording differs but the idea doesn't: a real choice, freely made, by someone able to make it.
| Where | The law | In plain words |
|---|---|---|
| England and Wales | Sexual Offences Act 2003, section 74 | You consent if you agree by choice and have the freedom and capacity to make that choice. |
| Scotland | Sexual Offences (Scotland) Act 2009, section 12 | Consent means agreement given freely. |
| South Africa | Criminal Law (Sexual Offences and Related Matters) Amendment Act 32 of 2007, section 1 | Voluntary or uncoerced agreement. There is none from someone asleep, unconscious, or in an altered state of consciousness through alcohol, drugs or medicine. |
The age of consent is 16 in England and Wales, as the Crown Prosecution Service (CPS) sets out, and 16 in South Africa, where the 2007 Act makes sexual acts with anyone aged 12 to 15 an offence even if they agreed (young people close in age excepted).
Consent in practice: four habits that keep it easy
- Ask in plain words. "Is this good?" and "Want to keep going?" beat guessing, and said with a grin they're no mood-killer.
- Listen to the whole answer. Silence, hesitation or a flat "I suppose" isn't a yes, and someone pulling away is answering too.
- Remember a yes can be taken back. Yes to kissing isn't yes to everything, and yes at ten o'clock can be no at ten past. When either of you stops, it stops.
- Too drunk to decide means no. If someone can't make a clear choice (slurring, stumbling, drifting off), there's no consent to be had tonight. Vuk'uzenzele, the South African government's publication, says it flatly: an intoxicated person cannot give consent.
Good manners do the rest: see casual hookup etiquette.
Is it illegal to share someone's intimate photos?
Swapping photos between willing adults is one thing; passing them on without consent is a crime in each place below.
England, Wales and Scotland
In England and Wales, section 66B of the Sexual Offences Act 2003 (added by the Online Safety Act 2023, in force since 31 January 2024) makes it an offence to share an intimate image without consent, or to threaten to; aggravated forms carry up to two years. Creating a sexual deepfake of an adult has also been an offence there since 6 February 2026, under section 66E of the same Act. In Scotland, disclosing an intimate photo or film, or threatening to, is an offence under section 2 of the Abusive Behaviour and Sexual Harm (Scotland) Act 2016.
South Africa
Section 16 of the Cybercrimes Act 19 of 2020, in force since 1 December 2021, makes it an offence to share someone's intimate image by message, app or online without their consent. Real and simulated images both count, and the penalty can be a fine or up to three years in prison.
Images already out there? StopNCII, from the Revenge Porn Helpline, turns each one into a digital fingerprint on your device and passes only that to the companies signed up, so they can find and remove copies. You must be the person pictured and 18 or over, now and when it was taken; if you were under 18 in it, NCMEC's Take It Down is the route. If such content turns up on XXX Direct, support takes it down fast, and our hookup scams guide covers sextortion.
Sexual health: condoms, tests and PrEP
Condoms, and if one splits
Free condoms come from NHS sexual health clinics and some GP surgeries and pharmacies. If one splits, the NHS says get urgent help from a pharmacist, a sexual health clinic, 111 or a GP.
Testing in the UK
NHS sexual health clinics are open to everyone, whatever your age, gender or sexuality, and their STI and HIV tests are free. You don't have to use your real name, and some clinics offer home testing kits for some STIs. The NHS sexual health helpline is 0300 123 7123.
Testing and condoms in South Africa
Public health facilities offer free HIV counselling and testing, says South Africa's government. Gauteng's clinics add STI testing and treatment and free condoms, says its health department, and the Western Cape Government says male and female condoms are free at its clinics. AIDS Helpline: 0800 012 322.
PrEP
PrEP is HIV prevention. On the NHS, PrEP is free from sexual health clinics, as tablets or, for some, an injection every two months. In South Africa, the government launched a twice-yearly PrEP injection in June 2026, starting at 360 public health facilities in six provinces.
When to get tested
The NHS says get checked if you're having sex with new people, because many STIs have no symptoms.
Help after a sexual assault
If something happened that you didn't agree to, it isn't your fault. Get medical help first, and soon: the NHS gives PEP for exposure in the last 72 hours.
In the UK
Rape Crisis England & Wales runs a 24/7 Rape & Sexual Abuse Support Line on 0808 500 2222, plus online chat, for anyone 16 or over. Rape Crisis Scotland's helpline is 08088 01 03 02, daily from 5pm to midnight, or text 07537 410 027. NHS sexual assault referral centres (SARCs) offer medical, practical and emotional support, and the NHS says you don't have to report to the police unless you want to.
In South Africa
Thuthuzela Care Centres, the National Prosecuting Authority's one-stop facilities for rape survivors at clinics and hospitals, let you report there or at a police station, now or later. If the examination happens within 72 hours, DNA evidence is taken and PEP given. The GBV Command Centre's 24-hour line is 0800 428 428, or *120*7867#, with an SMS option for people with a disability: send "help" to 31531.
If the other person was a member, report the profile; support answers by chat and messaging at any hour. Emergency numbers are in meeting a hookup safely; the site's protections are on the safety page and the UK and Mature South Africa section pages.
Sexual health and consent: your questions
What is the age of consent?
Sixteen in England and Wales, according to the Crown Prosecution Service, and sixteen in South Africa under Act 32 of 2007.
Can someone consent if they've been drinking?
A drink doesn't rule it out; being too drunk to choose does, under the law in England and Wales and in South Africa. Unsure? Stop.
How soon after sex should I get tested?
The NHS says some STIs take up to seven weeks after unprotected sex to show on a test, so ask the clinic whether you need a repeat. Worried about HIV? Don't wait: PEP must start within 72 hours.
Is PrEP free?
On the NHS, yes, from sexual health clinics; NHS inform says PrEP is free of charge in Scotland too. In South Africa, Department of Health guidelines say facilities should offer PrEP to anyone who tests HIV negative and asks.
