Abstinence

Abstinence is the term used to refer to the practice of never having sexual intercourse outside of marriage. Abstinence is deeply associated with conservative religions, and as such does not support the use of birth control, i.e. condoms. People who practice abstinence are known as being "abstinent".

Abstinence is not the same as cellibacy, which refers to the practice of never having sex at all, regardless of marital status.

Abstinence in teaching
People on the left and  right of the  political spectrum frequently argue as to how children in school should be taught on matters of sex.

Fundamentalist conservatives generally believe that students should not be educated properly about birth control in school and instead told that that thing in their trousers will kill an angel if it's used before you're married. Students are told this instead of informing them of birth control methods, which allows them to choose their own lifestyle instead.

Liberals generally believe that students should be educated properly about birth control, and how it does and doesn't always work (because we don't pretend that jonny's are 100% bulletproof). This way, students can make a choice for themselves, rather than having their parents beliefs forced upon them.
