Connection to Sexuality
Yes, strongly. “Impure” has historically been used to describe sexual behavior outside traditional norms (like premarital sex, adultery, or lustful thoughts). In religious and cultural contexts, women especially were judged as “impure” if they lost virginity outside marriage. Today, the sexual sense is still understood but considered old-fashioned or judgmental.
