sexual abstinence

Purity rings are worn by some youth committed to the practice of sexual abstinence. Sexual abstinence or sexual restraint is the practice of refraining from sexual activity for reasons medical, psychological, legal, social, philosophical, moral, religious or other. It is a part of chastity. Celibacy is sexual abstinence generally motivated by factors such as an individual's personal or religious beliefs. Sexual abstinence before marriage is required by social norms in some societies, or by law in some countries.

Abstinence may be voluntary (when an individual chooses not to engage in sexual activity due to moral, religious, philosophical, or other reasons), an involuntary result of social circumstances (when one cannot find any willing sexual partners), or legally mandated (e.g. in countries where sexual activity outside marriage is illegal, in prisons, etc.).
