Believe it or not, you can be celibate without being chaste, and chaste without being celibate. A celibate person is merely unmarried, usually (but not always) because of a vow of celibacy. The traditional assumption is that such a person is not having sex with anyone, which leads many to confuse the word with “chaste,” denoting someone who does not have illicit sex. A woman could have wild sex twice a day with her lawful husband and technically still be chaste, though the word is more often used to imply a general abstemiousness from sex and sexuality. You can always amuse your readers by misspelling the latter word as “chased.”
