adj. committed to being chaste; abstaining from sexual intercourse

Celibacy refers either to being unmarried or to sexual abstinence. Celibacy is sometimes used as a synonym for "abstinence" or "chastity." A vow of celibacy is a promise not to enter into marriage or engage in sexual intercourse. The term involuntary celibacy has recently appeared to describe a chronic, unwilling state of celibacy.
