Sex education in adulthood

Sex education in adulthood means continuing to learn about your body, pleasure, relationships, contraception and infection prevention after your teenage years. Many adults never had full sex education, and the questions change with each stage of life: a new relationship, moving in together, pregnancy, a break-up or a health problem.

Why adults need it too

The World Health Organization (WHO) defines sexual health as "a state of physical, emotional, mental and social well-being in relation to sexuality", not just the absence of disease. WHO adds that it matters throughout life. Learning as an adult helps you fill gaps, question myths and adapt what you know to each stage.

The figures make the case. According to WHO, more than one million curable sexually transmitted infections (STIs) are acquired every day worldwide among people aged 15 to 49, and most cause no symptoms. In Europe, the European Centre for Disease Prevention and Control (ECDC) reported more than 106,000 gonorrhoea cases in 2024, a 303% rise since 2015.

Communication: the basis of a satisfying sex life

Nobody can guess what another person wants or dislikes. Talking about desires, limits and worries improves intimacy and avoids misunderstandings. Some tips:

• Pick your moment: a calm chat works better than criticism mid-sex.
• Speak for yourself: "I'd like to try…" works better than "you never…".
• Listen without judging: including to what isn't said out loud.
• Accept change: desire and preferences shift over time.

Consent, every time

Consent is a free, informed agreement that can be withdrawn at any moment. It is not assumed because you are married, live together or have done it before. There is no valid consent if the other person is asleep, very drunk or under pressure.

Desire: what changes and what is normal

Desire is not constant. Stress, tiredness, parenting, some medicines and conflict all affect it. Many people, especially in long relationships, experience responsive desire: it appears after touching begins, not before. This is normal and not a sign of a problem. We explain it in spontaneous and responsive desire.

Contraception and family planning

Your choice of method can change over your life. Long-acting methods such as the implant or the IUD fail in fewer than 1 in 100 people a year. According to the US Centers for Disease Control and Prevention (CDC), external condoms fail about 13% of the time with typical use. Only condoms also protect against STIs. You can compare options in main contraceptive methods. If you are trying for a baby or have just given birth, see our pregnancy and postpartum guide.

STI prevention and testing

Many STIs cause no symptoms, so feeling well is not enough. The main tools are:

• Condoms: highly effective when used correctly from start to finish, though they protect less against herpes, syphilis and human papillomavirus (HPV), which can be on skin a condom does not cover.
• Vaccines: available against hepatitis B and HPV.
• Testing: the CDC recommends an HIV test at least once between ages 13 and 64, and repeat STI tests with new or multiple partners.

Common myths

• "I'm in a stable relationship, so I don't need to know more." Needs change, and an STI can go unnoticed for years.
• "Good sex has to be spontaneous." Planning intimacy is common and doesn't make it any less valuable.
• "Some pain is normal." Repeated pain during sex is not normal, and it can be treated.

When to get help

See your GP or a sexual health clinic if you notice pain, unusual discharge or sores on your genitals, if a partner has an STI, if you have had sex without protection, or if low desire is upsetting you. Sex therapists and psychologists can also help with relationship difficulties.
