Sex education is formal teaching about bodies, reproduction, consent, relationships, contraception, and infection. Good programs are accurate and matched to age. They name pleasure and they name risk without turning either into the whole story. Poor programs skip the parts adults find awkward and then wonder why teenagers invent the rest.

Parents still shape what a child believes about shame. Schools and clinics fill gaps when homes go silent. Adults who missed this education can get it later from clinicians, books, and honest friends. There is no graduation date after which you are forbidden to learn how a condom works.

Politics fights over this curriculum because sex sits next to values. The body facts do not change when a committee votes.

If you are teaching anyone, use real words for parts. Nickname games help nobody in a doctor’s office later.
