Sexual Education: Body, Puberty & Sexuality

Learn the basics of anatomy, development, desire and sexual response.

What is sexual education?

Sexual education provides information and skills for understanding bodies, relationships, consent, identity and sexual and reproductive health. Good education is age-appropriate, factual and respectful. It supports informed decisions rather than pressuring people toward any particular choice.

Anatomy and development

Human reproductive anatomy includes internal and external structures with different functions. Bodies vary in appearance and development. Puberty brings hormonal changes that may affect growth, skin, body hair, menstruation, erections, ejaculation, emotions and sexual feelings. Puberty does not occur on one exact schedule.

Sexual desire and arousal

Desire refers to wanting sexual activity; arousal includes physical and psychological responses. They do not always occur together, and neither response proves consent. Stress, sleep, medication, health, hormones, relationship dynamics and context can all influence desire and arousal.

Masturbation and myths

Masturbation is a common behaviour, but people differ in whether they do it. Myths that it inevitably causes infertility, blindness or permanent weakness are not supported by good medical evidence. If any behaviour causes pain, injury, distress or interferes with daily life, seek qualified advice.

Orientation and gender respect

Sexual orientation concerns patterns of attraction; gender identity is a person’s internal sense of gender. These are not the same concept. Use respectful language, avoid assumptions and recognise that people’s experiences differ.

When to seek care

Ask a qualified clinician about pain, concerning changes, puberty concerns, distress or questions that require individual assessment. A website cannot determine what is normal for a particular person.
