Sex is a mutual activity between consenting adults. It can include different acts and is not only intercourse. The core ideas are consent, communication, safety, and mutual pleasure.
Key body parts
- In people with penises: penis, glans, shaft, and testes.
- In people with vaginas: vulva (including labia and clitoris), vagina, uterus, ovaries, and cervix.
- Arousal and lubrication help make sex more comfortable and enjoyable for many people.
What happens during sex
- Consent: both people freely agree to participate; consent can be paused or withdrawn at any time.
- Arousal: physical changes such as erection and lubrication occur.
- Sexual activity: there are many options (vaginal, oral, manual, etc.); open communication about likes, dislikes, and boundaries is important.
- Aftercare: cuddling, talking, or simply checking in helps maintain respect and connection.
Safety, contraception, and STI prevention
To reduce risks, use condoms consistently and correctly; they protect against many sexually transmitted infections (STIs) and can be used with other contraception methods.
- Contraception options: hormonal methods (pills, patches, injections), long-acting reversible contraception (IUD, implants), or barrier methods.
- Pregnancy risk: vaginal sex without contraception can lead to pregnancy; plan accordingly.
- STI testing and regular check-ups are important if you are sexually active with new or multiple partners.
Communication and consent tips
- Ask for explicit consent and check in with your partner about comfort levels.
- Respect boundaries; if someone says no or pauses, stop immediately.
- Discuss contraception and STI history before sex; use protection that fits both partners.
