Safer sex basics
Not medical advice
No Strings Men is not a healthcare provider. We do not diagnose, treat, or give medical guidance. The information here is general wellbeing and signposting only. It is not complete, may not apply to your situation, and is not a substitute for speaking to a qualified clinician or sexual health service.
If you are worried about symptoms, exposure, or your health, contact your GP, a local sexual health clinic, or NHS 111 (England) for advice on where to get help. In an emergency, use emergency services.
Consent and communication
Clear, ongoing consent matters for any sexual activity. It is OK to pause, change your mind, or use plain words about boundaries and what you are comfortable with. If you ever feel pressured or unsafe, you can leave and seek help (including emergency services if you are at risk).
Barriers and risk reduction
External resources explain how barrier methods (such as condoms) can reduce the risk of many STIs when used correctly and consistently. They do not remove all risk. Combining different approaches (testing, communication, vaccination where offered) is something to discuss with a sexual health professional.
Do not buy prescription medicines online to "cover" a risk without medical advice. Wrong or incomplete treatment can harm you and others.
Sex without condoms (sometimes called barebacking)
People use different words for anal or vaginal sex without a condom. Whatever you call it, going without barriers usually carries higher STI risk than consistent condom use, including for HIV and other infections that pass through fluids or skin contact. Risk is not the same for everyone or every situation. Only a sexual health service can explain testing, prevention options, and what applies to you.
If you have sex without condoms, many people still use other tools to look after themselves and partners: regular testing, honest conversations about status and boundaries, and options such as PrEP or PEP where a clinician says they are appropriate. Public information from the NHS and sexual health charities describes these in plain language.
No approach removes all risk. If you are unsure what to do after a risk, contact a sexual health clinic or NHS 111 (England) promptly rather than guessing.
Cannabis and other substances ("420") and sex
Online, 420 often refers to cannabis. Recreational cannabis remains illegal in the UK outside very limited medical prescribing. Laws differ elsewhere if you travel.
Alcohol and other drugs can change how clearly you think, negotiate, or remember consent and safer sex plans. They can make it harder to use condoms correctly, notice discomfort, or stop if something does not feel right. That can increase STI risk and other harms, including situations where consent is unclear.
If you use substances, being open with yourself about those effects can help you plan ahead (for example agreeing boundaries while sober, sticking with people you trust, and knowing how to get home safely). For drug information and support in the UK, Talk to FRANK is a national starting point. For sexual health questions, use a clinic or GP as above.
